Used primarily as a reactive diluent and crosslinking agent in UV-curable coatings, inks, and adhesives. Its dual functionality allows it to participate in free radical polymerization, enhancing the speed of cure and improving the mechanical and chemical resistance of the final product. Commonly found in dental composites and prosthetics due to its ability to form strong, durable, and biocompatible polymer networks. Also utilized in specialty resins for 3D printing and in the formulation of pressure-sensitive adhesives where improved adhesion and toughness are required. Its hydrophilic nature makes it suitable for applications requiring moisture resistance and dimensional stability.
