Used primarily as a photoinitiator in UV-curable formulations, this compound plays a key role in polymerization processes triggered by ultraviolet light. It is especially effective in free radical polymerization systems, making it valuable in coatings, inks, and adhesives that require rapid curing under UV exposure. Its molecular structure allows for efficient light absorption and radical generation, leading to strong crosslinking and durable film formation. Commonly found in industrial printing, electronics encapsulation, and dental materials, it contributes to high reactivity and good stability in final products.
