FoamStar® ST 2439 is a defoaming molecule that defoams by a unique mechanism. Unlike conventional defoamers (mineral oil and silicone types), FoamStar ST 2439 defoams on a molecular level. It also has wetting properties not found in other conventional defoamers. FoamStar ST 2439 utilizes the FoamStar molecule compounded with polysiloxanes in a mineral oil-free system. FoamStar ST 2439 defoamer is very effective in defoaming high gloss paints based on acrylic and styrene acrylic latices.
