Used primarily as a UV absorber in polymer systems, this compound provides excellent protection against long-term UV degradation. It is especially effective in coatings, plastics, and adhesives where maintaining color stability and mechanical properties under sunlight exposure is critical. Its high thermal stability makes it suitable for use in high-temperature processing applications such as extrusion and injection molding. Commonly added to polycarbonates, polyesters, and acrylics to prevent yellowing and embrittlement. Also utilized in automotive coatings and industrial finishes for enhanced durability. Shows good compatibility with other additives like hindered amine light stabilizers (HALS), allowing synergistic effects in weather-resistant formulations.
