Arkema Has Optimistic View on Global Market
Arkema hosted its annual press breakfast during the ACS, where Eric Kaiser, Americas Business Director for Arkema Coating Resins, gave a brief review of market conditions and the company’s growth. According to Kaiser, the view from the United States is very optimistic. Even at the show, the general sentiment from customers was quite good, he noted. Europe is stabilizing and is returning to some growth. For high-growth economies like China and Brazil, growth has slowed down from peak levels, but is still high. As a company, Arkema is moving into a high-growth mode, with a goal of €8 billion in sales by 2016. The company had sales of €6.1 billion in 2013.
Dr. Francois Court, Marketing Director Coatex Group, spoke specifically about the European market. He stated that 2014 perspectives seem brighter, and that they are seeing positive signs from customers in southern Europe. The goal for zero emissions has been the driver in Europe for the past 15 years, and is really embedded into the way companies design paint. Another trend is the use of renewable raw materials, but the question remains, “Are people going to be willing to pay for this technology?”
At the booth, Arkema showcased every aspect of the company’s coatings market offerings, including new products, technologies, business resources and commitment to innovation and sustainability. Arkema’s representation at the event included subsidiaries Coatex and Sartomer; and Arkema business units Arkema Coating Resins, Arkema Fluoropolymers, Arkema Acrylic Monomers and Arkema Specialty Polyamides.
According to Richard D. Jenkins, Global Group President for Arkema Coating Resins, the company is focusing its resources on offering its customers more choices in both the raw materials they need for their formulations and in the way they do business with Arkema. “More choice leads to new opportunities – both for the customer and for the coatings industry in general,” Jenkins explained. “When formulators have greater resources at their disposal – in this case, raw materials – the potential for innovation and new ideas grows exponentially. Arkema’s job is to offer those choices, along with the expanded global support they need to innovate and realize their growth goals.”
Arkema illustrated greater choice by showcasing a wide range of new products and technologies. “All of Arkema’s product development initiatives have been about offering customers more choices,” Alain Mari, CEO of the Coatex business, said. “This includes new ways to approach problems such as environmentally friendlier coatings or water resistance, emerging application areas like white roof coatings or TiO2 replacement, and even greater latitude in the cost effectiveness of high-performance coating applications.”

By collaborating with formulators, customers, distributors and industry experts, five businesses within The Dow Chemical Company (Dow) have developed a broad portfolio of enhanced performance technologies that were highlighted at ACS. Dow Coating Materials, Dow Construction Chemicals, Dow Consumer & Industrial Solutions, Dow Epoxy, and Dow Microbial Control discussed and showcased these collaborative innovations.
Dow Coating Materials
Dow Coating Materials(DCM) showcased technology innovations that include FORMASHIELD™ 12 100% acrylic binder, a waterborne binder that offers active formaldehyde removal from ambient air when painted on walls of a room, RHOPLEX™ EZ Clean 1500 acrylic emulsion, a binder with advanced stain beading technology that helps make it fast and easy to clean up tough liquids, and EVOQUE™ pre-composite polymer technology, the 2013 winner of the U.S. EPA Green Chemistry Award.
DCM also introduced MAINCOTE™ IC acrylic resins. Unintended heat transfer from industrial infrastructure is an ongoing challenge to worker safety, equipment maintenance and energy efficiency. With the introduction of MAINCOTE IC acrylic resins, Dow is helping to create a new category of liquid insulation coating that provides a solution to this challenge, offering low thermal conductivity in an easy spray application.
“We want to provide paint formulators with a product that will help their industrial customers reduce costs and facilitate worker safety,” said Mary Rose Correa, North America industrial coatings field marketing manager, Dow Coating Materials. “Waterborne thermal insulation coating formulations containing MAINCOTE IC acrylic resins not only have safe touch properties at elevated temperatures, but also maintain target temperatures with notably lower energy usage versus without a coating,” she added.
Traditional insulation materials, such as fiberglass, polyurethane foam and other materials can be used to reduce heat transfer and energy loss, but can be expensive and hard to apply over complex geometries, such as valves and levers. These materials only mask the problem of corrosion under insulation (CUI), instead of solving it, potentially leading to costly maintenance and repairs.
Thermal insulation coatings formulated with MAINCOTE IC acrylic resins offer a solution to unintended heat loss and CUI. The resins are designed for use with low-thermal-conductivity fillers, and coatings formulated with them can replace the thick mechanical insulation that can mask CUI. Fiberglass and other industrial insulation materials typically require a separate moisture barrier or jacketing to keep out water to prevent corrosion issues.
Dow Construction Chemicals
Dow Construction Chemicals(DCC) offered a range of coating and construction chemical technologies that help facilitate high-performance, sustainable and energy-efficient products in the building and construction industry. DCC showcased painter’s caulk and other sealant formulations made with RHOPLEX 4400 polymer technology, which can be freed of the effects of plasticizer, resulting in reduced glossing, paint discoloration and mildew pick-up. In addition to its plasticizer-free benefits, RHOPLEX 4400 polymer also facilitates ultra-low formaldehyde, APEO-free, low-VOC formulations.
Dow Consumer and Industrial Solutions
Dow Consumer and Industrial Solutions(DC&IS)highlightedAMP™ 95 multifunctional neutralizer technology, which offers benefits throughout the coating life cycle.AMP 95 offers exceptional performance, low odor, excellent base strength, efficient pigment dispersion, and enhanced scrub resistance. DC&IS also offers additional compounds that offer unique benefits to formulators, such as oxygen and moisture scavenging, corrosion inhibition, and improved wetting. These specialty additives are sold under the trade names DMAMP-80™, ALKATERGE™ FLEXITANE ™, HYDROGUARD™ and ZOLDINE™.
Dow Epoxy featured differentiated products for civil engineering applications as part of its line of D.E.R.™ epoxy resins and diluents and D.E.H.™ curing agent. The business showcased technology that can help enhance performance and ease-of-application through benefits such as strong chemical resistance to protect tank linings and secondary containment applications, low emission technologies to enable healthier indoor spaces, low-temperature-curing products to help extend application seasons, and rapid-curing epoxies to reduce application time. The portfolio also offers solvent-free technologies, being manufactured without added solvent, including options for REACH-compliant curing systems with improved performance. The epoxy business also showcased the company’s specialty line for industrial coatings – the OUDRA™ series of resins and curing agents designed to help protect a wide range of assets from extreme conditions, while balancing the need for performance, respect of the environment, and value.
Dow Microbial Control
Dow Microbial Control (DMC) offered a portfolio of in-can and dry-film biocides designed to help protect products from microbial contamination. DMC highlighted plant hygiene solutions, featuring DOWICIL™ QK-20 antimicrobial, the fast-acting solution for clean-up of equipment, raw materials, wash water and finished products.
Dow Corning’s Antifoam Technology and New Surface Modifier
Dow Corning showcased its new silicone antifoam technology for architectural coatings. According to Gerald Witucki, Associate Scientist, Application Engineering Coatings, Resins and Additives, traditional mineral oil defoamers find compatibility issues in a number of systems (potential for haze and gloss reduction), and also offer limited effect on surface tension and decreased effectiveness in compliant formulations.
Witucki noted that silicone antifoams are effective at much lower dosage rates than organic antifoams, leading to significantly lower cost-in-use. They also tend to be much more persistent than organic antifoams. And silicone antifoams tend to be less reactive in the foaming medium, leading to fewer compatibility problems. Modern silicone foam technology provides a wide range of tailored structures to balance conflicting property requirement, including foam control, stability, surface appearance and recoatability.
“This is a true market opening,” he noted, as using a silicone defoamer for architectural coatings has never before been an option.
Dow Corning also highlighted its Dow Corning®52 Additive, an ultrahigh-molecular-weight silicone dispersion that gives formulators the unique advantage of customizing slip to precise levels while improving current coatings benefits. This proprietary surfactant can disperse in waterborne coatings and is suitable for use in industrial wood coatings, wood trim, inks, overprint varnishes and interior/exterior paints. It allows users to formulate a host of waterborne coatings that can significantly differentiate products with a range of desirable benefits, including but not limited to:
- Customizable slip;
- Improved scratch and abrasion resistance;
- Improved sandability;
- Enhanced anti-blocking;
- Good recoatability; and
- Good hand feel.
Dow Corning52 Additive will not negatively impact surface hardness, water resistance or intercoat adhesion, and will not decrease recoatability. It allows for easy incorporation into waterborne formulations during the let-down or post-additive manufacturing stages. Silicones have low surface tension and therefore orient to the air/polymer interface, which forms a very thin lubricating layer on the coating surface to reduce the coefficient of friction.
Eastman’s Problem-Solving Skills
Eastman’s booth looked significantly different than others at the ACS. With as few words as possible on its panels, and no products on display, the company chose to focus on its ability to solve problems for customers with its deep product line. The main graphic element to the booth panels were large puzzle pieces, which tied into its theme of helping customers find the missing piece of their formulation puzzle.
According to Maryellen Mantyla, Marketing Communications Manager, Additives and Functional Products, the company fielded a lot of great, application-specific questions throughout the show. Leaving the booth theme open, rather than directing people to specific products, allowed attendees to consider a lot of different options, and collaborate with Eastman on innovative solutions.
Emerald’s Newest Technologies
Emerald Performance Materials has made incredible developments for growth and innovation since ACS 2012, and was excited to return as an exhibitor to showcase new technologies for the coatings industry, as well as strategic investments, expansions and new operations.

CVC Thermoset Specialties has made several significant investments to increase capacity and efficiency for its specialty thermoset formulation products, in part due to increasing demand for products that meet critical performance characteristics for demanding end-use applications, including toughness, corrosion and impact resistance, and flexibility. In December, the group announced the addition of a new reactor train and improved product separation technology to nearly double capacity for its OMICURE™ line of catalysts and accelerators. In November, the CVC group also announced an initiative to increase capacity for its line of ERISYS™ epoxy reactive modifiers used to reduce viscosity and improve handling, processing, and application properties of formulations. The group debottlenecked the reactor train used to produce the line at its Maple Shade, NJ, facility. Debottlenecking and increased efficiency at the group’s Maple Shade facility were also designed to reduce environmental impact of the manufacturing operation.
Emerald Specialty Polymers completed construction on a new R&D pilot plantat its Akron, OH, facility in December to support R&D initiatives and expand the group’s range of Nychem™ latex emulsions, including emulsions that fall outside the traditional acrylonitrile-styrene-butadiene lattices. The new plant, which includes a 100-gallon pilot reactor, will also allow the group to work with customers to develop customized solutions.
Emerald Kalama Chemical has completed a series of recent investments and expansions and more than doubled its capacity for K-FLEX coalescents and plasticizers since 2011. The group completed the fourth expansion at its Kalama, WA, facility in August and also dedicated an additional reactor for production and R&D. The group opened a new global technical center in Kalama in August 2012 and added a K-FLEX operation at its Rotterdam, Netherlands facility in September 2012, greatly expanding the group’s worldwide reach. The group also brought an additional benzoic acid reactor train online in Rotterdam and signed onto a green deal energy cooperative to reduce emissions and reduce carbon footprint in the Port of Rotterdam. (As of May 2013, Emerald as a whole had cut emissions more than 50% since its formation in 2006.)
New Evonik Products Launched
After launching in Europe, the following products were featured from Evonik at the ACS.
• TEGO®Twin 4200 is the new universal substrate wetting additive for waterborne wood coatings, industrial coatings and printing inks, which can also be used in solventborne and even UV coatings. In addition to outstanding wetting and anti-cratering properties, TEGO Twin 4200 provides no foam stabilization.
• SILIKOPHEN®AC 900 and SILIKOPHEN AC 1000 were designed for the high-temperature applications of industrial objects, muffler coatings and oven coatings. Due to their ambient-temperature curing capabilities, a feature highly coveted by manufacturers, these resins permit energy-saving coating application of large objects that would otherwise prove difficult in a more traditional oven-cure.
Evonik also featured bright prospects for matte paints. With its new hydroxyalkylamide crosslinker, VESTAGON® EP-HA 368, Evonik has developed a cost-effective matting concept for the powder coating market. Customers can now benefit from a one-shot production process for manufacturing matte HAA powder coatings. Compared to the traditional dry blend method, a modified process using the new VESTAGON hardener allows manufactures to save time and resources. This less-complex manufacturing process requires only three process steps instead of four. The standard hydroxyalkylamide crosslinker is substituted by VESTAGON EP-HA 368.
Evonik also exhibited technology that makes automotive clear coats even more scratch-resistant. The company has developed an industrial-scale method for producing silane-modified binders for automotive finishes. The advantage of these binders is that silane groups increase crosslinking density, making it possible to create automotive finishes that are flexible yet harder, leading to improved scratch resistance.
The basic concept behind the new technology was already known: modifying classic binders with silanes noticeably improves the binder properties. This also applies to the polyurethane binders typically used for automotive finishes. Up to now, however, production of silane-modified polyurethane binders has been so complex and expensive that these products have only been made on a small scale for applications such as high-performance adhesives. For more general uses and for large-scale applications such as automotive finishes, however, there simply has not been enough available. The new technology from Evonik stands to change all of that.
The breakthrough came when Evonik developed its own manufacturing process for the silyl isocyanate IPMS, or (3-isocyanatopropyl) trimethoxysilane. It is the critical building block for producing silane-modified binders. Evonik has been producing IPMS in a new facility in Marl (Germany) since mid-2013. Dr. Ulrich Küsthardt, head of the Coatings & Additives Business Unit at Evonik, points out, “With the new facility, Evonik creates its access to IPMS and to a new group of customized, silane-modified binders.”
By using IPMS and selecting the right additional raw materials, Evonik can adapt coating binders to the needs of its customers.
One of the first applications for the new IPMS binders is the thin clear coating – only about 40 micrometers thick – that serves as the glossy top layer of an automotive finish. In addition to improved scratch resistance, the new systems are just as resistant to chemicals and the elements as traditional two-component polyurethane coatings. Plus, silane-modified binders are completely compatible with two-component polyurethane coatings and significantly improve their properties. For car manufacturers, that means being able to use their usual production lines for applying coatings that contain the innovative binder. Selected automakers have already taken the first steps toward approving clear finishes that have been modified in this way.
Dr. Hans Görlitzer, however, who works in the Coatings and Additives Business Unit at Evonik as Head of Business Development in the Crosslinkers Business Line, believes the new technology has even more potential. “We aim to open up access to silane-modified binders for other applications too.” As examples, he cites coatings for wood, plastics, metal, and high-tech adhesives. The key criterion here is that the silane-crosslinked clearcoats cure quickly enough at room temperature.
Huber’s Calcium Carbonate for Post-Consumer Content Applications
Huber Engineered Materials, a division of J.M. Huber Corporation, launched ReCal™ Platinum calcium carbonate for use as a component in building materials to generate various green building credits and in other demanding applications where certified post-consumer content is required.
ReCal Platinum is 50 percent by weight post-consumer content (third-party verified), with the remaining 50 percent post-industrial content (third-party verification pending) produced by a proprietary re-milling process (patent pending). It is a light gray color milled to a consistent median particle size and topcut. Two ReCal Platinum calcium carbonate products are offered, ReCal™ Platinum 8 and ReCal™ Platinum 20, which are milled to an 8- or 20-micron median particle size, respectively.
Post-consumer application possibilities are numerous. They include building materials used for various green building credits, which include the LEED®Program, National Green Building Standard™ Rating System and NSF/ANSI 140 and 332.
“ReCal Platinum is a win-win for Huber and the customer, as we both want to be at the forefront of environmental stewardship and sustainability,” said Lane Shaw, Technology and Business Development Director of Huber’s Ground Calcium Carbonate business. “Many of our customers are looking to achieve LEED credits and green-related certifications, and we’re able to successfully recycle calcium carbonate to offer a post-consumer product.”
A recent pilot program conducted between a paint operation and a carpet company has proven that the ReCal Platinum grades can be used successfully to create new consumer products. Calcium carbonate was recovered from the painting operation and taken to Huber’s Quincy, IL, calcium carbonate operation for re-milling, then sent to the carpet company for recycled carpet backing applications.
“We’re excited and pleased with the results we’ve seen from ReCal Platinum thus far, as we are just scratching the surface of what we think this product can achieve from both a performance and applications standpoint,” said Shaw.

Sustainable Solutions from LANXESS
LANXESS presented material protection products as well as organic and inorganic pigments that fulfill even the most exact requirements. The spotlight was on premium products for the coloration and preservation of coatings, paints, plasters and mortars.
“Our extensive and high-performance product portfolio actively reflects the megatrend of urbanization. American manufacturers of paints, coatings and coating materials – which represent a very important customer segment – can count on our products when it comes to sustainability, too,” remarked Dr. Hans-Peter Baldus, who is responsible for the pigment business of the LANXESS Inorganic Pigments (IPG) business unit in the United States.
The Inorganic Chemicals business unit presented ecologically safe iron and chrome oxides from the Bayferrox and Colortherm ranges for coloring coatings. The pigments are lightfast, weather-stable and very resistant to chemicals. The current range comprises more than 100 shades produced from the basic colors black, red, brown, green, yellow and orange. The production facilities for these pigments in Porto Feliz, Brazil, and Krefeld-Uerdingen, Germany, are SCS-certified. LANXESS IPG is thus the world’s only pigment producer to have received this certification. Scientific Certification Systems, Inc. is one of the leading companies for independent certification, and determines, for example, the proportion of recycled raw materials used in an industrial production process. “An evaluation of our processes revealed a recycling content of over 92 percent. This exceptional result makes a very good contribution to our sustainability strategy,” said Joerg Hellwig, Head of the Inorganic Pigments business unit at LANXESS. “As a next step, we are planning an audit of our facility at the Jinshan site in Shanghai, China.”
Pigments from SCS-certified production operations comply with LEED (Leadership in Energy and Environmental Design) and are thus safe for sustainable building. Already represented in over 40 countries, the LEED certification system evaluates and confirms the environmental, social and economic sustainability of buildings in their entirety. The evaluation parameters include energy efficiency, water conservation, CO2 reduction, eco-friendly indoor fixtures and fittings, and responsible use of all resources required. With this certification LANXESS IPG enables its customers to develop sustainable end products.
“The trend toward urbanization is driving the demand for environmentally friendly, sustainably produced iron oxide pigments. With our new facility in Ningbo, we are expanding our global production network to ensure we grow along with our customers,” explained Hellwig. A new plant with a production capacity of 25,000 metric tons per year is currently being built in the Ningbo chemical park on China’s east coast in which LANXESS will manufacture high-quality iron oxide red pigments. Here, the company will apply for the first time its optimized Penniman process in which improved water treatment and waste gas cleaning bring a high level of environmental sustainability. The plant, characterized by its particularly high energy efficiency, is designed to meet and exceed the latest environmental standards. “We are very proud of the fact that we are the first manufacturer of iron oxide pigments that is in a position to manufacture these bright, clean, yellow-shade red pigments in an environmentally friendly and consistent way,” added Hellwig. The new products from Ningbo will be marketed globally under the Bayferrox brand for use in the paints and coatings industries.
The Material Protection Products (MPP) business unit of LANXESS showcased high-performance fungicides and algicides that offer long-lasting antimicrobial protection for paints, varnishes and other building coatings. Preservatives from LANXESS help paints last longer during storage by preventing decomposition caused by microorganisms. In addition, other microbicides ensure that coatings provide lasting film protection after application by preventing algal and fungal attack on the film. Products from established brands Preventol, Sporgard, Veriguard and Biochek are on display. The film preservative Preventol A14-D – which is now EPA-registered in the United States – is being presented to the American market for the first time. The VOC-free formulation ensures that no molds or algae can grow on and damage dry coatings.
MPP is also focusing on formaldehyde- and VOC-free in-can preservatives for protecting water-based, eco-friendly coatings from microbial attack by bacteria, fungi and yeasts.
The Functional Chemicals (FCC) business unit is presenting pigment preparations based on organic and inorganic high-performance pigments from the Levanyl and Levanox ranges that make it possible to obtain brilliant hues with excellent lightfastness.
Due to their high weather resistance, special grades such as Levanox Yellow 6G-LF and Levanox Blue 4G-LF are ideal for outdoor use, for example. These inorganic dispersions are specially treated to prevent heavy pigment particles from forming a compact sediment if they settle. This means they can be completely homogenized again simply by stirring, even after prolonged storage.
Lawter’s High Bio-Renewable Alternatives
High bio-renewable alternatives to acrylic emulsions have been sought after in the aqueous printing ink industry during the last decades. Lawter exhibited a new rosin technology it has developed that provides a bio-based replacement for acrylics in packaging inks. These rosin dispersion products are marketed under the brand name SnowPack™ and can be used in combination with acrylics to increase the bio-renewable content. They were developed as a green alternative to the pure acrylic systems for the benefit of the ink and OPV formulator, printer and print buyer.
Michelman’s New Brand Identity
Michelman introduced its new brand identity at a press breakfast and conference at the ACS. According to Bob Poletti, Chief Marketing and Corporate Development Officer at Michelman, “Michelman is not the same company it was five or six years ago. In the economic downturn of 2008, when most companies were pulling back investment, we continued to push forward. We invested strategically in key areas of the world, and in core or complementary industry segments. We’ve added many talented associates who have helped position Michelman as thought leaders, and as a company who is able to think ahead to what will be the next solution. All of these investments and more have helped us reach the point where we can assure customers we will provide forward-thinking, proactive, environmentally friendly solutions.” The clean new brand mark symbolizes Michelman’s evolution, and acts as a signal to customers of Michelman’s commitment to forward-looking, agile solution development.

Momentive’s Patent-Pending Coating Modifier
According to Dan Weinmann, Global Segment Leader Epoxy Coatings and Civil Engineering at Momenitve, the ACS was an excellent show. “Show traffic has been very constant, and we’ve had quality contacts and content-rich discussions,” he noted. Weinmann also commented that the tone of the show was very optimistic. “Everybody has been in survival mode for the past few years,” he stated, noting that most people he spoke with were much more confident at this year’s event.
Momentive Performance Materials Inc. introduced a new patent-pending coating modifier that delivers an unexpected property set.New CoatOSil FLX™ coating modifier can improve coating flexibility while also maintaining or even enhancing corrosion resistance and gloss retention, helping to mitigate the embrittlement issues that often plague present silane-cured hybrid coating technologies. With this new technology, coating formulators may no longer have to sacrifice critical properties when seeking increased flexibility in a coating.
As an added benefit, the improved flexibility can produce a stronger, more protective coating, and the greater resistance to UV degradation allows the coating to look new longer. The technology can also help improve formulating latitude. Inherently low in viscosity, CoatOSil FLX is easy to mix into coating formulations; it can be incorporated into the grind paste or as a post-addition to the coating formulation with comparable efficacy. The coating modifier may be considered for low-VOC and HAPs coating systems.
Pigment Technology from New Brook International
New Brook International showcased several new pigment technologies. Brufatec®29070 is a high-performance, very strong and bright orange pigment. It assists the color formulator in filling the cadmium and molybdate orange color spaces that are changing due to REACH and other environmental regulations.

New Brook’s new metallic pigment, Super Gold 3000, has outstanding shine and coverage that is comparable to a gold leaf effect. This pigment fills a need in the market that is not currently addressed. It is an excellent choice for textile and other specialized inks.
Orion Specialty Carbon Black Provides Flexibility in Coating Design
Orion Engineered Carbons introduced Experimental Black XPB 412, a specialty carbon black that offers formulators more flexibility when creating new water- and solvent-based coatings. Designed for medium-color coating applications, Experimental Black XPB 412 has good coloristic properties and excellent dispersion behavior.
“We recommend the new product for all kinds of general industrial liquid coatings, both waterborne and solventborne,” said Thomas Papasso, Market Manager, Coatings, Orion Engineered Carbons. “It provides a balance between performance and cost, making it an ideal solution for companies producing products in this category.”
Experimental Black XPB 412 is the latest carbon black pigment from the new production line at the company’s Kalscheuren, Germany, plant. It benefits from a new after-treatment process Orion developed to increase the number of carboxylic groups on the surface of the carbon black pigment. The carboxyl groups enhance interaction with polar binders, and improve the dispersion process and stability of the carbon black pigment during coating production.
In waterborne coatings the outstanding dispersion behavior maximizes the efficiency of wetting agents used to improve coloristic properties. Used with a typical amount of wetting agent in water-borne coatings, Experimental Black XPB 412 with the new after-treatment process provides higher jetness than Orion SPECIAL BLACK 4, with neutral undertone rather than a brownish one. In solventborne coatings it imparts the same jetness and undertone as SPECIAL BLACK 4.
The company also presented COLOUR BLACK FW 255 carbon black pigment, the first launch of its new generation of specialty carbon blacks. Setting new benchmarks for high jetness, coloristic performance, and compatibility with both waterborne and solventborne systems, COLOUR BLACK FW 255 carbon black pigment enables formulators to maintain performance and coloristic properties while migrating to waterborne formulations. It is especially suited for automotive OEM and refinish systems.
Orion also exhibited Carbon Black XPB 545 for conductive and anti-static coatings. Introduced in 2013, XPB 545 meets or exceeds performance requirements for conductivity, dispersibility and cleanliness at lower concentrations than conventional conductive carbon blacks. It creates a coating film with deep jetness and high gloss.

100% Bio-Based Succinic Acid from Reverdia
As a first-time exhibitor at the ACS, Reverdia was happy and surprised at the level of interest in bio-succinic acid. The company highlighted the benefits of Biosuccinium, a 100% bio-based succinic acid that offers a more sustainable alternative to conventional raw materials such as fossil-based succinic acid, adipic acid or terephthalic acid.
Today, succinic acid is not yet a commonly used monomer in the resins and coatings industry. Nevertheless, various studies have already demonstrated the technical feasibility in a multitude of applications, with equal or even improved performance when compared to the typical fossil-based benchmark. Examples include improved hardness and flexibility of powder coatings, shorter drying times in alkyds and better chemical resistance in polyurethane-based systems.
As the operator of the world’s first dedicated large-scale plant for the commercial production of succinic acid from renewable resources, Reverdia offers producers of resins, coatings, adhesive and sealant products an opportunity to reduce environmental impact, become less dependent on fossil resources, and differentiate their products on the basis of an improved sustainability profile.
Biosuccinium is manufactured by means of a novel and proprietary biotechnology process, a yeast-based fermentation process that is unique in delivering consistent product quality. It is also environmentally sensitive, uses non-fossil raw materials, sequesters carbon dioxide (CO2), is energy efficient, and does not produce unnecessary by-products.
According to Marcel Lubben, President of Reverdia, the introduction of Biosuccinium meets the need to reduce the environmental impact. “As we move from a fossil-fuel-based economy to a more sustainable bio-based one, manufacturers are looking for alternative solutions. Biosuccinium provides a sustainable alternative to fossil-based raw materials used for resins, coatings, adhesives and sealants,” he said. “Biosuccinium presents a wide range of new market opportunities. We have successfully identified opportunities for using Biosuccinium as raw material for alkyd, polyester, polyurethane and composite resins. In addition, chemical derivatives of succinic acid, which are in part bio-based, provide alternative sustainable solutions to the chemicals industry. These are in various stages of development and include Dimethyl succinate (DMS), branded Provichem®2511 Eco provided by Proviron, Biosuccinium-based polyester polyols, Plasticizers based on Biosuccinium, Quinacridone and DPP pigments,” he added.

WACKER’s Extensive Range of Products
WACKER presented its extensive range of coatings, coating additives, binders and wood stain products. This broad selection of silicone and polymer-based chemistries offer the formulator customized solutions and performance-enhancing benefits that help bring added market-value. Below is a list of just some of the products exhibited at the show.
Architectural Coatings and Binders
VINNAPAS® EF8300 is the latest development in VAE binders for high-performance coatings. Available in the Americas region as a binder for architectural coatings, VINNAPAS EF8300 combines high performance, such as good block resistance, wet adhesion and scrub resistance with lower environmental effect, and is ideal for flat through gloss finishes. It has a performance comparable to pure acrylics and exceeds that of vinyl acrylics and blend systems. It thus provides an acrylate-free option to replace traditional binders in high-end coatings, allowing the paint formulator to meet today’s VOC regulations.
The product meets foreseeable environmental regulations because it is produced without the use of APEOs and allows the formulation of architectural coatings that are low VOC (<5 g/L), very low residual monomer (<200 ppm) and low formaldehyde without the addition of coalescing solvents. It is therefore GS-11-compliant and meets any foreseeable environmental regulations, such as CARB, OTC, LATCO and SCAQMD.
VINNAPAS EF8001, with availability in the Americas region, is a versatile interior-coatings binder for low-odor and low-VOC paints. A premier binder for flat and mid-sheen paints, it combines superior low-odor and low-VOC capability with excellent performance and cost-in-use-benefits. It enables formulations of low-odor and low-VOC paints (<5 g/L), since it has very low residual-monomer content (<200 ppm) and does not need organic solvents or coalescing agents. Its odor profile is noticeably subdued; especially compared to standard vinyl acrylic technology. Furthermore, it is produced without the use of APEOs and features low formaldehyde. It is GS-11-compliant and meets applicable environmental regulations, including proposed reductions in VOCs.
SILRES®BS 45 binder is used in the formulation of masonry coatings where water repellency is desired. A water-dilutable solventless emulsion of silicone resin, SILRES BS 45 is used in the production of silicone resin emulsion paints and plasters where it is employed as the main binder. Properly formulated, products incorporated with this product are characterized by high permeability to water vapor and C02, slow water absorption and decreased dirt pick-up in a breathable exterior coating. Additional benefits include imparting a mineral appearance to the substrate and extended longevity. Furthermore, an excellent beading effect is achieved when both SILRES BS 45 and SILRES BS 1306 are incorporated together into the formulation.
SILRES BS 1306 is a solventless, water-thinnable emulsion of a polysiloxane modified with functional silicone resin. It is an additive used in the manufacture of breathable, aqueous masonry coatings and aqueous primers to enhance water repellency, water resistance and water-vapor permeability with visible beading effect. It also improves the processability and antiblock characteristics of the aqueous coatings and is low VOC (<0.5 g/L). When used in combination with SILRES BS 45, an excellent beading effect is achieved.
SILRES BS 310 is a solventless, water-thinnable emulsion of a polysiloxane modified with functional silicone resin that promotes open time and wetting with excellent leveling properties in aqueous coatings. SILRESBS 310 is used in an undiluted form as an additive for aqueous indoor paints and coatings to effectively improve workability of the formulation. Low in VOC (<0.5 g/L), it is very compatible with indoor paints; it is especially effective in reducing lap marks and improving hydrophobicity in high humidity areas such kitchens and baths.
SILRES BS 1360 is a nonionic, solvent-free, water-dilutable emulsion of a reactive polysiloxane used in the manufacture of aqueous primers, thus increasing hydrophobicity in paints and deck stains and enhancing water repellency, water resistance and water-vapor permeability. SILRES BS 1360 is a low VOC (<0.5 g/L) additive that produces excellent water beading effect and is used in the manufacture of interior paints, silicone resin emulsion paints and plasters, and highly filled emulsion coatings.
SILRES WH 80 A is a water-reducible, solvent-free emulsion of a siloxane that can be used to increase beading and water repellency of cellulosic substrates. The modification of water-reducible organic polymers, such as alkyds or acrylic latex formulations with SILRES WH 80 A silicone wood hybrid, increases water repellency and beading after exposure to UV radiation. Thus it imparts excellent short- and long-term beading effect in wood stain formulations. It is low VOC before and after curing according to EPA Method 24 and is UV stable, resistant to cracking, peeling and blistering. Additionally, wood stain coating formulations using SILRES WH 80 A retain color and gloss after weathering and exposure to the elements.
