Used as a reactive diluent and co-monomer in UV-curable coatings, inks, and adhesives due to its low viscosity and fast polymerization rate. Enhances adhesion, flexibility, and chemical resistance in polymer formulations. Commonly employed in dental materials, contact lenses, and hydrogels because of its biocompatibility and ability to modify hydrophilicity. Also utilized in personal care products like hair sprays and conditioners for film-forming and water solubility properties. Plays a role in controlled drug delivery systems and functional textiles when copolymerized with other monomers.
