BIBB 515 is widely used as a photoinitiator in the polymerization process, particularly in UV-curable coatings, inks, and adhesives. Its ability to generate free radicals upon exposure to UV light makes it essential for initiating the curing of monomers and oligomers, resulting in rapid and efficient solidification of materials. This property is highly valued in industries requiring fast production speeds, such as printing, packaging, and electronics. Additionally, it is employed in the manufacturing of dental composites and other medical devices where precise and quick curing is critical. Its stability and efficiency under UV exposure ensure consistent performance in various industrial applications.
