Used as a UV stabilizer in polymers, particularly in coatings, adhesives, and high-performance plastics. It helps prevent degradation caused by ultraviolet light, improving the durability and lifespan of materials exposed to sunlight. Commonly applied in automotive coatings, industrial finishes, and transparent polymer systems where clarity and long-term weather resistance are important. Also functions as a synergist in antioxidant formulations, enhancing the effectiveness of primary stabilizers.
