Gelest Antimicrobial Punctures Organisms’ Cell Wall

Gelest featured its BIOSAFE® silicon-based antimicrobial that imparts bacteriostatic, fungistatic and algistatic properties to coatings and resins for manufactured goods. It protects materials used in a wide range of consumer and industrial applications where microorganisms can cause staining, pitting, deterioration or foul odors, including healthcare, building products and sporting goods. The organosilicon technology is more cost-effective and faster acting than silver-based additives, avoids discoloration and is nonleaching.

BIOSAFE technology provides an environmentally sustainable means of prolonging the useful life of consumer and industrial products. The antimicrobial component kills microorganisms by effectively puncturing and rupturing the organisms’ cell wall. By comparison, conventional antimicrobials kill by leaching into the cell, where they are metabolized and interfere with critical life processes. This conventional mode of action has been shown to cause microorganisms to mutate and adapt, becoming resistant to the antimicrobial. BIOSAFE products avoid this problem.

The antimicrobial effectiveness and safety is verified by independent GLP/EPA-registered labs.

TOLSA Showcased New Series of Additives  

TOLSA, based in Madrid, a leading global supplier of specialized additives for the paint and coatings industry, showcased its portfolio of rheological additives based on high-purity sepiolite technology.

TOLSA highlighted its broad range of products and the performance of its high-growth U.S. additives business. TOLSA has built a strong foundation in the U.S. by producing unique additives for water-based and solvent-based systems. The company has experienced strong growth over the last several years, and its long-term strategy is to expand its resources and capabilities with new investment in technology, manufacturing, capital and personnel.

“With our broad product portfolio we are firmly positioned as a strategic supplier to the U.S. market,” said Michelle Mercurio, sales director for TOLSA USA. “Our innovative technology has now been validated in the U.S., and we continue to see strong results as our products gain market share.”

TOLSA highlighted the PANGEL® series of rheological additives for water-based and solvent-based paints and coatings. The product range is based on a wide variety of special clays, including sepiolite, attapulgite, montmorillonite and saponite with each sharing the capabilities of easy build up, shear thinning and thixotropic gel structures.

PANGEL additives are composed of extremely high-purity sepiolite minerals. TOLSA developed the technology required for purification and production of highly efficient and very low-crystalline silica additives, which are unique in the industry. These two key characteristics make them extremely good candidates as attapulgite additive alternatives.

A key feature of PANGEL technology is its ability to yield fewer defects when incorporated into a coatings system, thus providing a competitive advantage for the end user. PANGEL products are particularly efficient in architectural and industrial coatings where solids content and filler density often drives strong variations in coatings stability.

For waterborne systems, TOLSA offers the PANGEL S series, produced from high-purity sepiolite with outstanding suspension and antisagging capacity unaffected by electrolytes. It is normally used as a co-thickener with HEC or associative thickeners for improving syneresis and sedimentation, and replaces attapulgite thickeners at half dosage. Other products for waterborne systems include the PANGEL W series, specifically developed to enhance thickening and antisagging properties with water retention and excellent brushability, and the PANGEL M series, produced from high-purity bentonite for easy gelling and dispersing capacity.

Products for solvent-based systems include the PANGEL B series, which are rheological organoclay additives based on high-purity sepiolite with extra performance and additional suspension capacity, antisagging and homogenizing; and the PANGEL OM series, rheological organoclay additives based on high-purity bentonite for easy incorporation. The PANGEL OMD series consists of self-activated organoclay additives based on high-purity bentonite for easy incorporation into solvent-based systems.

The company also featured PANSIL® UltraSpheres Spherical Ceramic MicroSpheres. UltraSpheres deliver improved performance, reduced resin use, lower cost and fewer VOCs in a range of applications.

PANSIL UltraSpheres are economical, high-performance silica alumina ceramic microspheres used as fillers in a wide range of paints, coatings, mastics and other construction materials. Compared to irregular-shaped and partially spherical fillers, the 100% spherical shape of these microspheres provides improved processing and performance.
