Used primarily in the production of UV-curable inks, coatings, and adhesives, where it functions as a photoinitiator to enable rapid polymerization and curing under UV light. It is also utilized in the manufacturing of optical lenses, films, and UV-curable personal care products like nail coatings, enhancing clarity, durability, and resistance to UV degradation. In the cosmetic industry, it serves as a component in formulations requiring UV-initiated stabilization to prevent material breakdown from light exposure. Additionally, it is applied in the synthesis of specialty polymers and chemicals, improving performance, stability, and photo-reactivity in industrial processes.
