This chemical is primarily used as a light stabilizer in polymers and plastics to prevent degradation caused by UV radiation. It is particularly effective in polyolefins, such as polyethylene and polypropylene, where it enhances the durability and lifespan of products exposed to sunlight, such as outdoor furniture, automotive parts, and agricultural films. Additionally, it is employed in coatings and adhesives to maintain their performance and appearance under prolonged UV exposure. Its ability to scavenge free radicals makes it valuable in protecting materials from oxidative damage, ensuring they retain their mechanical properties and color stability over time.
