Widely used as a photoinitiator in UV-curable systems, this compound efficiently generates free radicals upon exposure to ultraviolet light, enabling rapid polymerization of acrylates and other monomers. It is especially effective in clear coatings, inks, and adhesives due to its high reactivity and ability to initiate curing even in thick or pigmented sections. Its performance in dual-cure systems and low migration characteristics make it suitable for applications requiring durability and low odor, such as in printing, electronics, and dental materials.
