UV Absorber 400 is widely used in the formulation of coatings, plastics, and adhesives to protect materials from the damaging effects of ultraviolet (UV) radiation. Its primary application is to prevent UV-induced degradation, such as discoloration, embrittlement, and loss of mechanical properties, in polymers and other sensitive materials. In the automotive industry, it is incorporated into paints and coatings to maintain the appearance and durability of vehicle exteriors exposed to sunlight. Additionally, it is used in packaging materials to protect contents from UV light, extending shelf life and preserving product quality. In construction, it enhances the longevity of outdoor structures and materials like PVC pipes and window frames by reducing UV-induced wear. Its compatibility with various polymers makes it a versatile additive in industries requiring UV stabilization.
