Used as a reactive diluent and crosslinking agent in UV-curable coatings, inks, and adhesives due to its high reactivity and ability to improve hardness and chemical resistance. Employed in polymer modification to introduce alkyne functionality, enabling further chemical reactions via click chemistry, especially in research and specialty material development. Applied in dental composites and electronic encapsulation materials where rapid curing and strong, durable networks are required. Serves as a building block in synthesizing functional polymers and copolymers with tailored properties for coatings, adhesives, and 3D printing resins.
