UV - **6 Chemical name:2&#**9;-(2&#**9;-Hydroxy*3&#**9;-tert-buty*5&#**9;-methyl-phenyl)**-chlorobenzotriazole Molecular formula:C*7H*8N3OCL CAS No. ********5 Properties: UV***6 is a important ultraviolet absorber of bonzotriazole series, which is stable, nontoxic, higher absorbency for ultraviolet ray. Specifications: Appearance Light yellow powder Melting point, oC ******1 Volatile matter, % 0.5max Ash content, % 0.*5max Transmissivity **0nm *7%min, **0nm *8%min Purity, % *9min Use: UV **6 is especially suited for polyolefin and cold cured polyesters. 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 polyolefin compounding and molding processes. In the use for the UV protection of polyester, UV **6 does not form colored complexes with the metallic salts used for the curing process of these resin. It is also used for photosensitive materials and coatings and so on. Packing: in *5 kg net poly-ply paper bags or fiberboard drum.
