Molecular defoamers: Resolving stability and compatibility problems

Though surfactants allow waterbome coatings to wet low surface energy substrates even in high-speed applications, they often stabilise foam. Traditional defoamers can cause surface defects or storage stability problems. New silicone-free defoamers eliminate foam and microfoam by attacking foam stabilisation on a molecular level, minimising side-effects and reducing the total additive package needed.
