Used as a photoinitiator in UV-curable systems, particularly in inks, coatings, and adhesives. It enables rapid polymerization upon exposure to ultraviolet light, offering efficient curing even under low-intensity UV sources. Its high reactivity and ability to generate free radicals make it suitable for clear coatings and pigmented systems. Also employed in 3D printing resins where fast curing and good depth of cure are required. Exhibits good thermal stability and compatibility with various monomers and oligomers, enhancing formulation flexibility.
