Used as a reactive diluent and functional binder in radiation-curable coatings, inks, and adhesives. Its low surface tension and good flexibility make it suitable for improving adhesion and scratch resistance in UV-curable formulations. Commonly applied in protective coatings for plastics, printing inks, and electronic encapsulants where fast curing and durability are required. Also serves as a compatibilizer in multi-component polymer systems due to its amphiphilic character.
