BYK® -315 N

BYK® -315 N by BYK is a solution of a polyester-modified polymethylalkylsiloxane. It is a silicone-containing surface additive for solvent-borne coating systems. Improves the flow and leveling and in some formulations also has a defoaming effect. Exhibits slight reduction in the surface tension, slight increase in surface slip and shows no blushing in clear coats after water immersion test. The formation of Bénard cells is also prevented and gloss is increased. BYK® -315 N is recommended for automotive-, industrial-, architectural-, and protective coatings. Recommended dosage is 0.05-0.6% of additive based upon total formulation.
