Used as a photoinitiator in UV-curable systems, this compound plays a key role in polymer chemistry, especially in inks, coatings, and adhesives that cure upon exposure to ultraviolet light. Its ability to absorb UV light efficiently and generate free radicals makes it suitable for initiating polymerization of acrylate-based monomers and oligomers. It is often selected for applications requiring deep cure and good surface hardness due to its molecular structure with extended conjugation from naphthyl groups. Additionally, it finds use in specialty printing technologies and dental composites where controlled, rapid curing is essential.
