Used primarily as a photoinitiator in UV-curable systems, this compound plays a key role in polymer chemistry. It efficiently generates free radicals upon exposure to ultraviolet light, making it suitable for initiating polymerization in coatings, inks, and adhesives. Its ability to absorb UV light and undergo cleavage or hydrogen abstraction reactions allows rapid curing under low-intensity UV sources. It is especially effective in formulations where deep cure and good film formation are required. Due to its molecular structure, it exhibits good compatibility with various monomers and oligomers, enhancing the curing speed and final material properties in acrylate-based systems.
