Viochem UV-326

Viochem UV-326 by Nanjing viochem is Phenol, 2-(5-chloro-2h-benzotriazole-2-yl)-6-(1,1-dimethylehthyl)-4-methyl. Acts as a UV absorber. Has a low volatility at high temperatures and high resistance to thermal degradation. Viochem UV-326 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, it does not form colored complexes with the metallic salts used for the curing process of these resins.
