FoamStar® ST 2438 is a 100% active defoamer compound combining a hyper-branched FoamStar polymer with high-end organo-silicones. It delivers fast foam knockdown with high efficiency. This defoamer does not reduce the gloss of high gloss paints and coatings, making it effective in difficult-to-defoam high gloss formulations. It ensures fast bubble-break versus conventional defoamers, effectiveness against microfoam, no separation or settling, very good persistence, and suitability for deep and clear/neutral bases.
