Used as a photostabilizer in polymer materials, particularly in plastics and coatings exposed to UV radiation. Its primary function is to absorb UV light and prevent degradation of the material, thereby extending the lifespan of outdoor applications such as automotive parts, building materials, and agricultural films. It is especially effective in polycarbonate and acrylic systems where long-term clarity and mechanical strength are required. Also utilized in some specialty inks and adhesives to maintain color and structural integrity under sunlight exposure.
