Used as a photoinitiator in UV-curable systems, particularly in coatings, inks, and adhesives. It helps initiate polymerization when exposed to ultraviolet light, enabling fast curing and improved film formation. Exhibits good thermal stability and is effective in free radical and cationic curing processes. Also employed in printing inks due to its ability to promote rapid drying and enhance surface hardness. Shows compatibility with various monomers and oligomers, making it suitable for clear coatings and high-performance industrial applications.
