Light Stabilizer 770

Name: Light Stabilizer 770
SKU: 0

Light Stabilizer 770 is a highly effective hindered amine light stabilizer (HALS), chemically known as bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate. This product effectively prevents photo-oxidative degradation of polymer materials under UV radiation by scavenging free radicals and decomposing hydroperoxides. With low volatility and excellent thermal stability, it is particularly suitable for plastic products requiring long-term outdoor use.
