Widely used as a photoinitiator in UV-curable systems, this compound efficiently generates free radicals upon exposure to ultraviolet light, enabling rapid polymerization of acrylate-based resins. It exhibits low oxygen inhibition, performing effectively even in the presence of air to minimize surface tackiness. It is particularly effective in clear coatings, inks, and adhesives where deep cure and low yellowing are critical. Its high reactivity under UV light makes it suitable for applications requiring fast curing speeds and excellent surface hardness. Commonly found in wood, plastic, and metal coatings, it performs well in both thin films and pigmented systems. Due to its good thermal stability and low migration tendency, it contributes to the durability and long-term performance of the cured material.
