BYK® -331

Polyether modified dimethylpolysiloxane copolymer. Acts as a silicone based surface additive for solevnt-borne, aqueous, and UV-curable systems. Provides improved substrate wetting. Imparts increased surface slip. Exhibits improved anti-blocking properties. Avoids the formation of Bénard cells. Possesses improved leveling and gloss. Offers a medium reduction of the surface tension of paint systems. Used in solvent-borne, aqueous and UV-curable printing inks and overprint varnishes.
