Used as a crosslinking agent in polymer chemistry, particularly in the formulation of UV-curable coatings and inks. It enables rapid curing upon exposure to ultraviolet light, improving hardness, chemical resistance, and durability of the final film. Also employed in adhesives and electronic encapsulants where low shrinkage and high reactivity are required. Its difunctional vinyl ether groups support efficient cationic polymerization, making it suitable for advanced lithography and 3D printing applications.
