Used as a photoinitiator in UV-curable coatings and inks, this compound facilitates rapid polymerization upon exposure to ultraviolet light. It is particularly effective in formulations requiring deep cure and low yellowing, making it suitable for clear coatings and sensitive printing applications. Its solubility in a variety of organic solvents allows easy integration into resin systems. Additionally, it contributes to improved adhesion and surface hardness in final cured films.
