Used primarily as a photoinitiator in UV-curable coatings, inks, and adhesives, it facilitates rapid polymerization under UV light exposure. It is also employed in the production of printed circuit boards and microelectronics, where its ability to generate acid upon irradiation aids in photolithography processes. Additionally, it serves as a key component in advanced material synthesis, particularly in the development of high-performance polymers and resins. Its stability and efficiency make it a preferred choice in industrial applications requiring precise and controlled curing mechanisms.
