Product Description: Used primarily as a highly effective light stabilizer in polymers, this compound protects materials from degradation caused by UV radiation. It is commonly added to plastics, coatings, and adhesives to prevent yellowing, cracking, and loss of mechanical strength during outdoor exposure. Its hindered amine structure scavenges free radicals formed under sunlight, significantly extending the lifespan of polymer-based products. Frequently employed in agricultural films, automotive parts, and exterior building materials where long-term weatherability is essential. Also compatible with other stabilizers, allowing synergistic formulations for enhanced performance.
