BYK-320

BYK 320 is a silicone-containing surface additive that provides a slight reduction of surface tension and slight increase of surface slip. It provides good leveling properties with defoaming abilities. BYK 320 prevents problems like ghosting and telegraphing. It can be used in solvent-borne systems and also recommended for ambient curing systems. BYK 320 additive provides benefits like leveling and defoaming, particularly for non-polar to medium polar systems. Its defoaming effect intensifies with increasing polarity. It helps reduce surface imperfections and improves finish. BYK 320 is suitable for use in formulations where a smooth finish and absence of surface defects is required.
