Product Description
UV Absorber 326 CAS 3896-11-5
UV 326 is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability for plastics and other organic polymers. UV Absorber 326 is especially suited for polyolefins and cold cured polyesters. UV 326 exhibits strong absorbance in the 300-400 nm region and minimal absorption in the visible region (> 400 nm) of the spectrum. The absorption maxima are at 312 nm and 353 nm (e = 15600 l/mol·cm) in chloroform solution.
Guidelines for use:1. Polyolefins: It is recommended to use UV-326 with a HALS type light stabilizer system for best results. The recommended concentrations range for PP applications from 0.1-0.5%,for PE applications from 0.1% to 0.4%. 2. Polyester resins: The recommended levels for normal polyester resins range from 0.2% to 0.3%, while for chlorinated, flame retardant polyester resins the recommendation is 0.5%.
Packing:
20 kg or 25kg fiber drum or carton box, net weight, with an inner PE liner.
