Safe to use and sustainable, TEGO® Foamex 8820 and 8850 defoamer concentrates from Evonik provide a bio-renewable content of more than 55%. These oil-based defoamer concentrates reportedly exhibit the same defoaming power as siloxane-based products and may be used in compliance with many regulations, such as Swiss Ordinance (Part A), FDA, and others. TEGO Foamex 8820 and 8850 are 100% active renewable oil-based products and don’t contain any solvents, biocides, or mineral oil.
TEGO Foamex 8820 is very powerful and shear stable, ideal for use at the grinding stage. It contains more than 55% renewable content. TEGO Foamex 8850 is easier to incorporate and more compatible. This “softer” defoamer with more than 95% renewable content is the first choice for the let-down stage. Developed for printing inks and varnishes, they are very suitable for food contact applications.
“Our additives portfolio provides a growing number of products containing bio-based raw materials. We’re continuously working on expanding our offerings to fulfill this important market need,” said Courtney Thurau, head of market segment printing inks.
