Widely used as a photoinitiator in UV-curable systems, this compound plays a key role in initiating free radical polymerization upon exposure to ultraviolet light. It is especially effective in clear coatings, inks, and adhesives where rapid curing is required under low-intensity UV light. Due to its ability to penetrate pigmented formulations, it is suitable for both transparent and colored systems. Commonly found in printing inks, wood coatings, and electronic materials, it enables fast production speeds and low energy consumption. Its relatively low volatility and good solubility in monomer mixtures make it a preferred choice in various industrial curing applications.
