Technical Datasheet | Supplied by Songwon
SONGSORB® 3280 by Songwon is a benzotriazole-based UV absorber for plastics. It is a strong absorber of ultraviolet radiation in the 290~400nm region. This additive possesses a high degree of photostability-photochemical energy absorbed in the ultraviolet region is dissipated as thermal energy. SONGSORB® 3280 features strong UV absorption, low initial color, good solubility in plasticizers as well as monomers, moderately low volatility, and very good compatibility in a wide variety of substrates. It can be used in combination with phenolic as well as phosphite antioxidants, and HALS to optimize performance in outdoor use. Recommended for polyolefins, PVC, styrene homo and copolymers, ABS, acrylic polymers, unsaturated polyesters, thermoplastic urethanes, moisture cured polyurethanes, polyacetals, polyvinylbutyral and two component epoxies & urethanes.
