Widely used as a UV absorber in polymers, coatings, and plastics to prevent degradation caused by sunlight. It stabilizes materials against UV-induced discoloration, cracking, and loss of mechanical strength. Commonly added to polyolefins, polycarbonates, polyurethanes, and acrylics during processing. Also found in automotive coatings, industrial finishes, and adhesives where long-term weatherability is critical. Effective in both clear and pigmented systems, providing protection over a broad UV range. Compatible with other stabilizers like hindered amine light stabilizers (HALS), often used in synergistic blends for enhanced performance. Used in outdoor applications such as construction materials, agricultural films, and exterior automotive parts.
