FoamStar® ST 2434



FoamStar® ST 2434 is effective in high gloss paints and coatings based on acrylic, styrene acrylic and vinyl acrylic latex. FoamStar® is a defoaming molecule that defoams by a different mechanism. Unlike conventional defoamers (mineral oil or silicone), FoamStar® ST 2434 defoams on a molecular level. It also has wetting properties not found in other conventional defoamers. FoamStar® ST 2434 utilizes the FoamStar® Molecule compounded with polysiloxanes in a mineral oil-free system.
