Used primarily as a UV absorber and antioxidant in polymers, this compound helps prevent degradation caused by sunlight and oxidation. It is especially effective in protecting plastics, coatings, and adhesives from yellowing, cracking, and loss of mechanical strength during prolonged outdoor exposure. Commonly incorporated into polyolefins, polyurethanes, and acrylics, it enhances the durability and lifespan of automotive parts, construction materials, and packaging films. Its ability to stabilize against thermal and photo-oxidative stress also makes it valuable in industrial lubricants and resins.
