Used as a photoinitiator in UV-curable formulations, enabling rapid polymerization upon exposure to ultraviolet light. Commonly applied in coatings, inks, and adhesives where fast curing and low yellowing are required. Offers good solubility in polar solvents and monomers, making it suitable for clear coat systems and sensitive printing applications. Provides efficient radical generation with minimal odor, contributing to improved working conditions and product stability.
