This chemical is primarily used as a light stabilizer in polymers to prevent degradation caused by UV radiation. It is commonly incorporated into plastics, coatings, and synthetic fibers to enhance their durability and longevity when exposed to sunlight. Its application is particularly valuable in outdoor products such as automotive parts, agricultural films, and construction materials, where resistance to weathering and UV-induced damage is critical. Additionally, it helps maintain the color and mechanical properties of polymers, ensuring they remain functional and aesthetically pleasing over time.
