Evonik Coating Additives is set to introduce two innovative defoamers, TEGO Foamex 16 and TEGO Foamex 11, at the American Coatings Show (ACS) 2024, April 30 - May 2, at the Indiana Convention Center in Indianapolis. These new additives are designed to improve the sustainability and performance of waterborne architectural coatings.

TEGO Foamex 16 is a siloxane-based defoamer concentrate that provides an exceptional balance of defoaming efficiency and compatibility, particularly for low to medium PVC coatings.  TEGO Foamex 11, a siloxane-based defoamer emulsion, is optimized for high PVC coatings. With 15 percent active ingredient, it is a highly effective, more environmentally friendly alternative to traditional mineral oil-based defoamers.

Michael Zink, Head of Evonik Coating Additives Americas, emphasizes the importance of these new products: “The launch of TEGO Foamex 16 and TEGO Foamex 11 shows how Evonik Coating Additives, together with our customers, is leading the way to more sustainable coatings. These products meet the growing demand for sustainable solutions that deliver exceptional performance. By setting a new industry standard, we are demonstrating that it is possible to achieve outstanding results while meeting the most stringent environmental regulations.”

Defoamers are essential components in coating formulations because they prevent and eliminate foam during the manufacturing, filling and application processes. Foam can cause defects in coatings, such as pinholes or cratering, which compromise the aesthetic and protective qualities of the final product. TEGO® Foamex defoamers are designed to effectively address these challenges, ensuring a smooth, flawless finish and optimal application properties.
