SONGSORB® 3280

Technical Datasheet | Supplied by Songwon
2-(2'-Hydroxy-3',5'-di-t-amylphenyl)benzotriazole. Acts as a strong absorber of ultraviolet radiation in the 290~400nm region. Has a high degree of photostability - photochemical energy absorbed in the ultraviolet region is dissipated as thermal energy. 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. Can be used in combination with phenolic as well as phosphite antioxidants, and HALS to optimize performance in outdoor use.
