Used primarily as a photoinitiator in UV-curable coatings and inks, it plays a crucial role in initiating polymerization reactions when exposed to ultraviolet light. This chemical is valued for its efficiency in generating free radicals, which helps in the rapid curing of coatings on various substrates like paper, plastic, and metal. Its application extends to the manufacturing of adhesives and printing plates, where quick curing times are essential. Additionally, it is employed in the production of optical lenses and electronic components, ensuring durable and high-quality finishes. Its stability under UV exposure makes it a reliable choice in industries requiring precise and efficient curing processes.
