Benzoin methyl ether is widely used as a photoinitiator in ultraviolet (UV) curing applications. It is particularly effective in the polymerization of coatings, inks, and adhesives when exposed to UV light. This chemical helps initiate the curing process, ensuring rapid and efficient hardening of materials, which is essential in industries like printing, packaging, and electronics. Additionally, it is utilized in dental composites and sealants, where quick curing under UV light is critical for patient comfort and procedural efficiency. Its ability to produce free radicals upon UV exposure makes it a key component in photopolymerization processes.
