Used primarily as a photoinitiator in UV-curable coatings and inks, it facilitates the polymerization process under UV light, making it essential in industries like printing, packaging, and electronics. It is also employed in the production of adhesives and sealants, where rapid curing is required. Additionally, it serves as an intermediate in the synthesis of specialty chemicals and organic compounds. Its stability and efficiency under UV exposure make it a valuable component in advanced material manufacturing.
