Widely used as a UV absorber in polymers and coatings, this compound provides excellent protection against ultraviolet radiation-induced degradation. It is particularly effective in stabilizing polyolefins, polycarbonates, and acrylics exposed to outdoor environments. Its molecular structure allows for strong absorption in the UV range (typically 300–400 nm), preventing chain scission and discoloration. Commonly formulated into plastics, adhesives, and clear coatings where long-term weatherability is required. Also found in automotive finishes and exterior building materials due to its thermal stability and compatibility with other additives like hindered amine light stabilizers (HALS). Shows low volatility and good resistance to extraction, making it suitable for applications requiring extended service life under intense sunlight.
