ADSORB 326
ADSORB 326 is called UV-326 is a UVabsorber of the hydroxyphenyl benzotriazole class, especially suited for polyolefins and cold cured polyesters.
Chemical Name: Bumetrizole；Or 2-(3-tert-Butyl-2-hydroxy-5-methylphenyl)-5-chloro-2H-benzotriazole; 2-(5-Chloro-2H-benzotriazol-2-yl)-6-(1,1-dimethylethyl)-4-methylphenol
Introduction
UV- 326 is a UV absorber of the hydroxyphenylbenzotriazole class, which imparts outstanding light stability to plastics and other organic substrates.
especially suited for polyolefins and cold cured polyesters.
UV- 326 has a wide range of indirect food approvals in polyolefins. It has a low volatility at high temperatures and high resistance to thermal degradation and can therefore be used without significant loss or decomposition in the polyolefin compounding and molding processes. In the use for the UV protection of polyester resins, UV- 326 does not form colored complexes with the metallic salts used for the curing process of these resins.
Synonyms: UV-326; Tinuvin 326; HRsorb-326; BUMETRIZOLE; Sumisorb 300; ACETOSTAB 326; UV ABSORBER 326; Absorber UV-326
