Used as a reactive diluent and crosslinking agent in UV-curable coatings and resins. Provides improved hardness, chemical resistance, and adhesion in industrial coatings. Commonly applied in printing inks, electronic encapsulants, and protective films due to its ability to enhance cure speed and mechanical properties. Its aromatic and alicyclic structure contributes to high refractive index and thermal stability, making it suitable for optical materials and specialty polymers.
