BYK-W 940

BYK W 940 is a wetting and dispersing additive for mineral fillers as well as inorganic and organic pigments. It stabilizes the solid particles in resin systems and prevents the settling of fillers and the flooding/floating of pigments. BYK W 940 is primarily used in color pastes and gel coats based on unsaturated polyester resins. BYK W 940 prevents the settling of pigments and fillers in formulations for advanced material applications. It contains a polysiloxane copolymer to reduce flooding/floating and provides benefits such as improved stability, dispersion and rheology control which are crucial for developing high performance advanced materials.
