  • Applications

    2-Hydroxyethyl acrylate (CAS 818-61-1) is a versatile monomer used to synthesize polyacrylates for coatings, paints, inks, and adhesives; its acrylate group plus a pendant hydroxyl enables post-polymerization functionalization, crosslinking, and hydrophilic modification; it is commonly employed as a reactive diluent or comonomer in UV-curable coating and ink formulations and as a feedstock for hydroxy-functional polymers and specialty resins; it may also be used to prepare hydrogel-forming polymers for advanced applications.
