Used as a reactive diluent in UV-curable coatings and resins, enhancing crosslinking density while maintaining low viscosity. Its hydroxyl and oxetane groups enable efficient cationic polymerization, improving hardness, chemical resistance, and adhesion in electronic encapsulants, optical materials, and protective coatings. Also serves as a building block in synthesizing polyurethanes and pharmaceuticals due to its bifunctional reactivity and thermal stability.
