Used primarily as a reactive diluent and crosslinking agent in UV-curable coatings, inks, and adhesives. Its hydroxyl group enables improved adhesion to polar substrates and allows further chemical modification, such as urethane formation. Commonly found in dental composites and prosthetics due to its biocompatibility and ability to form durable, transparent polymers. Also employed in the synthesis of functional polymers for biomedical applications, including hydrogels and drug delivery systems. Its low viscosity helps in formulating high-solids systems with reduced volatile organic content.
