2-Hydroxyethyl Acrylate is a clear to slightly yellow, viscous liquid with a mild, acrylate-like odor. It is primarily used as a reactive monomer in the production of acrylic resins and copolymers, offering excellent adhesion, flexibility, and hydrophilicity. This compound is widely applied in the manufacture of coatings, adhesives, sealants, and hydrogels. Due to its hydroxyl functionality, it enhances crosslinking and chemical reactivity in polymer systems. 2-HEA is also used in UV-curable formulations and biomedical materials, such as contact lenses and wound dressings. It is compatible with a wide range of monomers, including methacrylates, vinyl acetate, and styrene.
