TEGO® Foamex 883

Polyether siloxane copolymer, contains fumed silica. Used as a defoamer concentrate for waterborne formulations in architectural coatings, flexo and gravure inks. Provides very good defoaming effect in the grind. Exhibits good long-term effectiveness at low temperatures. Is highly effective. Prevents foam formation during production and application of waterborne coatings and printing inks. Destroys pre-existing foam and prevents air occlusions. Possesses the greatest possible effectiveness and compatibility especially when added to the let-down and in clear coats, owing to their optimized particle size. Main areas of applications include pure acrylic emulsion, styrene acrylic emulsion, vinyl and EVA emulsions, PU dispersions, and hybrid systems.
