Used primarily in the polymer industry to enhance the durability and longevity of materials exposed to ultraviolet (UV) radiation. It is commonly incorporated into plastics, coatings, and adhesives to prevent degradation caused by sunlight, such as discoloration, cracking, or loss of mechanical strength. Its effectiveness makes it suitable for outdoor applications, including automotive parts, construction materials, and packaging. Additionally, it is valued for its compatibility with various polymers and its ability to maintain material performance under harsh environmental conditions.
