Benzoin Isopropyl Ether is primarily used as a photoinitiator in ultraviolet (UV) curing applications. It is particularly effective in initiating the polymerization of monomers and oligomers when exposed to UV light, making it valuable in industries such as coatings, inks, and adhesives. Its ability to facilitate rapid curing under UV exposure enhances production efficiency and improves the durability and performance of the final products. Additionally, it is employed in the manufacturing of printed circuit boards and other electronic components, where precise and quick curing is essential. Its compatibility with various substrates and formulations further broadens its utility in UV-curable systems.
