Chimassorb 119/Light Stabilizer 119 CAS 106990-43-6 is a highly effective light stabilizer that acts as a shield to prevent degradation of polymers and other materials exposed to sunlight. Its advanced formula provides superior UV absorption and inhibits the formation of free radicals, significantly extending the life of the final product. This makes it ideal for industries such as plastics, coatings and textiles, where protection against UV-induced degradation is critical.
