Used primarily as a photoinitiator in UV-curable coatings, inks, and adhesives. It facilitates rapid polymerization when exposed to ultraviolet light, making it essential in industries requiring fast-drying and durable finishes. Additionally, it finds application in the production of optical lenses and electronic components, where precise curing is critical. Its stability and efficiency in initiating cross-linking reactions make it a valuable component in advanced material manufacturing.
