Used primarily as a light stabilizer in polymers and organic materials, this compound effectively protects against UV degradation. It is commonly added to plastics, coatings, and adhesives to extend service life by preventing yellowing, cracking, and loss of mechanical strength under prolonged sunlight exposure. Its application is especially valuable in automotive coatings, exterior paints, and transparent polymer films where long-term clarity and durability are critical. The compound functions by absorbing harmful ultraviolet radiation and dissipating it as heat, thus interrupting the photo-oxidative degradation process. It is often used in combination with other stabilizers for enhanced performance.
