Chisorb® 320 is one of a family of substituted benzotriazoles which protect against ultraviolet radiation. It has a low pKa and a hindered phenolic group. As a result, the molecule is more stable to acid and alkali, and less affected by the reducing and oxidizing agents commonly used in polymerization and curing. Also, it is much less sensitive to metal containing ingredients which cause discoloration, impaired performance and other problems. This pale yellow, crystalline powder should prove valuable as a light protective agent for polyolefins and cold-cured polyester resin.
