Used as a reactive diluent and crosslinking agent in UV-curable coatings, inks, and adhesives. Enhances adhesion to polar substrates such as metals and plastics due to its carboxylic acid group. Improves flexibility and durability in polymer formulations. Commonly employed in dental composites and bone cements for its biocompatibility and ability to copolymerize with other acrylic monomers. Also utilized in the synthesis of functional polymers for controlled release systems and hydrogels.
