This chemical is primarily used as a photoinitiator in UV-curable coatings, inks, and adhesives. It plays a crucial role in initiating polymerization reactions when exposed to ultraviolet light, enabling the rapid curing of materials. Its efficiency in generating free radicals under UV exposure makes it valuable in industries requiring fast and durable finishes, such as automotive, electronics, and packaging. Additionally, its stability and compatibility with various formulations enhance its utility in producing high-performance, scratch-resistant, and glossy surfaces.
