Used primarily as a photoinitiator in UV-curable coatings and inks, it facilitates rapid polymerization when exposed to ultraviolet light. This makes it valuable in industries such as printing, packaging, and electronics, where quick-drying and durable finishes are essential. Additionally, it is employed in the production of adhesives and sealants, enhancing their curing efficiency and performance. Its role in UV curing processes contributes to energy efficiency and reduced environmental impact compared to traditional thermal curing methods.
