Used primarily as a crosslinking agent in polymer formulations, this compound enhances thermal and mechanical stability of coatings and adhesives. It is especially effective in UV-curable systems, such as inks, varnishes, and electronic encapsulants, where it contributes to rapid curing and improved surface hardness. Its rigid biphenyl structure supports high glass transition temperatures in resulting polymers, making it suitable for high-performance industrial applications. Additionally, it finds use in dental composites and optical materials due to its clarity and durability upon polymerization.
