JADEWIN UV327

JADEWIN UV327 by Qingdao Jade New Material Technology is a 2-(2'-hydroxy-3',5'-di-tert-butylphenyl)-5-chlorobenzotriazole. Acts as strong ultraviolet (UV) light absorber (in the 290~400 nm region). Possesses high degree of photo-stability (photochemical energy absorbed in the ultraviolet region is dissipated as thermal energy). Exhibits good initial color, low volatility, excellent stability to heat and light, superior wash fastness. The low pKa and high hindrance of the phenolic group result in low sensitivity to metal containing ingredients in polymer formulation - catalysts residues & metallic driers. Compatible with polypropylene and polyethylene as well as cold cured polyesters & polyurethanes. JADEWIN UV327 is particularly suitable for dyes, and pigments. Can be used in combination with phenolic &phosphite antioxidants, and HALS to optimize performance in outdoor use. Listed in AICS, DSL, IECSC, EINECS, ENCS, ECL, PICCS and TSCA.
