Used as a reactive diluent and crosslinking agent in UV-curable coatings and adhesives. It helps reduce viscosity while enhancing cure speed and improving hardness and chemical resistance of the final polymer network. Commonly applied in printing inks, protective coatings, and electronic encapsulants where fast curing and durable films are required. Its difunctional structure supports the formation of dense polymer networks, making it suitable for high-performance industrial formulations.
