8:55 am - 9:25 am

The Smart Way to Coatings

Alessia Venturi, Editor & Co-Founder, IPCM

In the last decade, the field of industrial coatings has experienced a strong development of paint and coating products driven by the demand for sustainability, higher performances and appealing finishes. The field of powder coatings in particular has experienced the transformation from low-cost industrial finishing products (1980s and 1990s) to a highly technological, sustainable finish with a premium quality, durability, appearance and state-of-the-art functions. In short: smart coatings. The presentation will show a series of examples of smart coatings with their related industrial applications, including the most recent developments (anti-viral, low-cure, hyperdurable, high-performance anti-graffiti and much more).


9:30 am - 10:00 am

Graphene/Wax Composites for Improved Anticorrosion

Richard Czarnecki, Vice President, Micro Powders, Inc.

Graphene oxide is a carbon-based material similar to carbon nanotubes and fullerenes. This nanosized black powder has been shown to improve corrosion resistance in protective coatings. Being a nanopowder, graphene oxide has a very high surface area and is extremely difficult to wet and disperse in coating systems. Industrial hygiene issues have been a deterrent to the broader use of graphene oxide in powder coatings. This presentation will provide information on composite powders based on combinations of graphene oxide with polyolefin waxes. The resulting graphene oxide composite powders are easier to use and safer to handle in laboratories and manufacturing facilities. Corrosion resistance data will be presented to demonstrate the benefit of graphene oxide modification in coatings applied over both bare and FePO4 pretreated cold rolled steel substrates. A second-generation graphene composite powder suitable for both water- and solvent-based coatings will also be presented.

Weathering Results of Colorful Fluoropolymer Powder Coatings

Mark Ryan, Marketing Manager, Shepherd Color Co

Powder coatings provide an excellent method for coating a number of building products where exterior durability is required. The optimum systems are based on fluoropolymer resin systems and highly durable color pigments. The standard for the colored pigments are a class known as CICPs (Complex Inorganic Color Pigments) that have the ultimate in durability and inertness while providing bright colors. A study was initiated that looks at the weathering of CICPs in FEVE resin systems in a wide range of tests including QUV-B, concentrated natural weathering, Northern Industrial (U.S.), and Southern Florida. A wide range of CICP classes were used to provide data on a wide range of possible color matching.


11:10 am - 11:40 am

Coloristic Performance of Carbon Black in Powder Coatings

Trinh Nguyen, Technical Marketing Manager, Orion Engineered Carbons

This presentation will provide a comprehensive report surveying the coloristic performance including jetness, undertone, gloss and haze in both full tone and grey tone of carbon blacks in powder coatings. The study was conducted using carbon black in an epoxy-polyester hybrid and polyester system with HAA and TGIC crosslinkers. The final findings indicated that binder systems had the most influence on coloristic properties of carbon black. Bead and powder forms of the same carbon black showed no differences in colorimetric performances of the system. For typical powder coatings, it was recommended to use 1.0%-2.0% loading of carbon black (by weight, on total formulation) to obtain the opaque appearance. In the hybrid system, the oxidized gas black had inferior coloristic performance than non-oxidized types. In the polyester/HAA system, the non-oxidized gas black provided better pigment stabilization than the oxidized type. In general, for high jetness with bluish undertone application, high-color furnace black or high-color gas black was recommended. Low to medium furnace black or lamp black were determined to be suitable for low to medium jetness applications. It was also recommended to use coarser grades such as regular furnace black or lamp black for tinting application.


11:45 am - 12:15 pm

Impact of Pigment Finishing on Powder Coating Performance

Bonnie Piro, Technical Marketing Manager, Sudarshan North America

Organic pigments are synthesized molecules that result in providing a fairly narrow color (chroma and hue) around the color wheel, and within that pigment chemistry or color index there is a small window for color shifting. However, how you “finish” the pigment – wash, surface treat, dry, mill, etc., can greatly impact the pigment’s performance in a powder coating. In this presentation, we will explore the impact of various finishing steps on powder coating properties such as gloss, pellet flow and overbake stability.

Keynote Presentation: Back to the Future – A Look Back to See Ahead

Kevin Hales, Automotive Market Innovation Manager, Powder Coatings; AkzoNobel Coatings Inc

Powder Coating is positioned for a resurgence as new application opportunities present themselves in new automotive architectures. With the focus on growth of electrification, environmental compliance, energy consumption and overall performance, new areas of the vehicle are being considered for powder. As we explore the history of powder coating, we witness some extraordinary successes, so why hasn’t powder experienced the growth or use as a mainstream coating technology as compared to liquid? But more importantly, why is that about to change?


9:00 am - 9:30 am

A New Powder Coating Catalyst for Low-Temperature Bake Systems

Matt Salvi, Technical Sales Specialist, King Industries

Thermoset powder coating systems have been a key growth area in recent years as they provide increased resistance and performance properties. However, at temperatures below 200 °C, conventional catalysts can have trouble achieving full cure. Our new low-temperature-cure powder catalyst is designed to help formulators increase capacity while reducing energy and manufacturing costs. This highly active catalyst accelerates the epoxy/acid reaction for powder coatings while providing great chemical resistance and crosslink density. Our recent study compares our catalyst to conventional imidazole-type powder coatings catalysts in both thin-film and thick-film direct to metal applications. Our product shows improved final film properties at the low-temperature-bake schedules compared to the imidazole’s, without affecting color or appearance. We also discuss the improvements in safety and handling that our product provides.


9:35 am - 10:05 am

An Investigation into High-Temperature Epoxy Powder Coatings Formulated Using Benzophenone Tetracarboxylic Dianhydride (BTDA)

Vinay Mishra, Technical Development Manager, Jayhawk Fine Chemicals Corp.

Epoxy powder coatings offer a range of functional properties based on the overall formulation. High-temperature service, dielectric strength and chemical resistance are typical benefits. Dianhydrides are a unique class of curatives that enable high-temperature performance while using the simplest solid epoxy resins (SERs) based on bisphenol A. This presentation will review such performance from BTDA, benzophenone tetracarboxylic dianhydride, showcasing the results from a collaborative study on the topic. The presenter will focus on the development of high Tg (glass-transition temperature) with respect to variables such as the epoxy resin EEW, the formulation’s anhydride/epoxide stoichiometry and the cure profiles employed. Relevant data from thermal analysis techniques DSC and DMA will be shared.

10:35 am - 11:05 am

Next-Generation White Pigment Additive for Cost-Effective White and Colored Powder Coatings

Douglas Huff, Technical Accounts Manager, FP Pigments

FP Pigments produces a range of products for use in the coatings market to help reduce overall raw material costs. Designed as a partial replacement for TiO₂, our unique composite product, composed of TiO₂ encapsulated in high-purity PCC, has been successfully shown to replace between 10 and 30% of existing TiO₂ in powder coating formulations. Our presentation will describe the functionality of these pigments, and their performance in a range of interior white powder coatings. We will also discuss the potential for further cost savings through a reduction in the level of colored pigments used in tinted systems.


11:10 am - 11:40 am

Novel Synthetic Silica for Matting Powder Coatings

Bob Lin, Sr. Technical Manager, Evonik Industries

Powder coatings have continued to broaden their application to protect a greater range of substrates. With this expansion, more chemistries are being developed for differing substrate compositions. These include lower-temperature cure to address heat-sensitive substrates and/or lower energy consumption to reduce cost. These applications also require aesthetics that require consistent matte finishes. Although there are several additives technologies being employed, the stringent need for greater uniformity in the final coating is still a challenge.
In this study, the presentation reviews the range of available additive technologies that are currently being employed for matting powder coatings, then introduces a novel synthetic silica technology and examines its impact on matting in powder coatings. The study will look at how this influences processing of powder, usage of the novel synthetic silica, main effects on matting and other performance characteristics of the final powder coating. The results will provide a comparable overview of how the new novel synthetic silica performs versus current available technologies.


11:45 am - 12:15 pm

Powder Coating Preparation Control of Surface Defects For FEVE Resin Systems

Connie Przeslawski, Technical Service Engineer, AGC, Inc.

Paint formulators can spend an immense amount of time and resources screening various additives to remedy defects on cured surface coatings. However, in some cases, the processing parameters prior to spray application may be the cause of significant changes in defects for powder coating systems. We compared various preparation methods to changes in surface appearance and physical performance for FEVE resin-based powder systems over metallic substrates. This study will utilize accelerated corrosion testing to evaluate how a powder system’s preparation can affect the topcoat’s overall performance.

Digitalizing Surface Texture for Powder Coatings

Lan Njo, Color Researcher, AkzoNobel Coatings, Inc.

In powder coatings, there is a growing trend towards textured surfaces, especially in the architectural segment where both coarse and fine textures are often used. Traditionally, the quality of textured (powder coating) surfaces is checked by visual inspections. In this presentation, we will describe our investigations into BYK-Gardner’s new instrument, the spectro2profiler, with which we are preparing for the digitalization of quality control of textured surfaces. With this device, we can measure surface topography, allowing us to measure the structural properties of textured coatings.
We collected a large set of textured panels and performed a visual experiment in which a group of observers assessed pairs of panels. Next, we measured the panels with the new device, and correlated the instrumental with the visual data. This way, we derived a method to objectively evaluate the structural quality of powder coatings, both fine and coarse, in a consistent, precise and standardized manner, which can lead to digital tolerances for texture and reduce complaints.
Furthermore, by collecting all measurements in a database, we can better monitor our processes and improve customer communication by sharing data, and improve the formulation by providing additional data, thereby reducing the lead time for customers.


2:30 pm - 3:00 pm

The purpose of this presentation is to present allnex’s findings that demonstrate this achievement.


3:05 pm - 3:35 pm

Field-Applied Thermoplastic Epoxy Powder Coating Development for Girth Weld Protection

Clairene Bazilio, Research Engineer, Therma Vault Systems Inc.

There is sustained interest in the pipeline coating industry to develop multi-functional, single-layer protective coatings that can replace two- and three-layer systems with similar or better performance.
This work reports the development of an experimental powder coating formulation that provides both the high adhesion and corrosion resistance properties of epoxies as well as the flexibility and toughness of thermoplastics. The use of epoxy-based thermoplastic resin material presents an opportunity to develop stand-alone, high-performance pipeline coatings with base layer adhesion and top layer toughness typically seen with multi-layer coatings.
The dual properties of this experimental epoxy-based thermoplastic coating were investigated to protect buried field joints from corrosion and external loads. Experimental powder was applied on the girth welds using a portable and repeatable flame spray method. The coating was produced in a one-step process without the need for post-application heating. The coated girth weld pipes were buried for two years. Exhumed girth welds were found well-shielded by the coating without any rust, coating disbondment or physical damage. This new generation of thermoplastic-based epoxy coating provides alternatives to standard industry epoxy coatings due to its dual functionality and ease of application.
