Chemical Name: 2-(2'-Hydroxy-3'-t-butyl-5'-methylphenyl)-5-chlorobenzotriazole
Molecular Formula:C17H18ClN3O
Molecular Weight: 316
CAS No.:3896-11-5
Properties
A benzotriazole type ultraviolet absorber that has the effect of absorbing longer wavelength ultraviolet light.
volatile low at high temperature, good thermal stability, has certain absorption of long wave ultraviolet.
Application
It is a representative benzotriazole ultraviolet absorber with excellent ultraviolet absorption ability, especially strong absorbance in the range of 300~400nm, and no absorption in the visible region (>400nm). UV326 has extensive indirect food contact approval in polyolefin with low volatility and heat stability. Suitable for polyolefin (especially food grade products), polyvinyl chloride, polyamide, ABS resin, AS resin and polyurethane.
Storage
Keep container tightly closed in a cool, well-ventilated place.
The recommended max. storage life is 12 month when stored under normal conditions.
