BYK® -332

Polyether modified dimethylpolysiloxane-copolymer. Acts as a silicone based surface additive for coatings. Provides better substrate wetting. Increases the surface slip. Improves leveling (long wave). Exhibits improved anti-blocking properties. Possesses improved leveling and gloss. Improves the wetting-up of the surface. Prevents the formation of Bénard cells. Reduces the spraydust and dirt sensitivity. Can be added to isocyanate hardeners. Used in solvent-borne, solvent-free, and aqueous coatings.
