Used as a UV stabilizer in polymers and coatings, protecting materials from degradation caused by sunlight. It is effective in plastics, adhesives, and automotive finishes due to its ability to absorb ultraviolet radiation and prevent photo-oxidative damage. Also employed in specialty inks and clear coats where long-term clarity and durability are required. Its non-metallic structure makes it suitable for applications needing low discoloration and high compatibility with organic matrices.
