BYK W 940 is a wetting and dispersing additive that prevents the settling of pigments and fillers. It stabilizes solid particles and prevents flooding or floating. BYK W 940 is primarily used in color pastes where it reduces settling of fillers. It contains a polysiloxane copolymer to reduce floating. BYK W 940 is recommended for systems using mineral fillers or inorganic and organic pigments. As a wetting and dispersing additive, BYK W 940 provides benefits such as uniform dispersion of pigments and fillers, improved stability and workability. These properties help achieve consistent quality and performance.
