Used primarily as a photoinitiator in UV-curable systems, this compound plays a key role in initiating polymerization reactions upon exposure to ultraviolet light. It is especially effective in clear coatings, inks, and adhesives where deep cure and low yellowing are required. Its amine functionality enhances reactivity and allows for efficient curing even in low-light conditions or in thicker films. Commonly found in formulations for dental composites and 3D printing resins, it supports rapid curing and strong final product performance.
