  • Applications

    Urethane dimethacrylate (CAS 41137-60-4) is a multifunctional monomer widely used in UV-curable resin systems for coatings, sealants, and inks, where it forms crosslinked polymer networks upon UV exposure. It also serves as a key component in dental resin composites, delivering high strength and rigidity for dental restorations. In adhesives and sealants, it acts as a reactive monomer to produce robust bonding formulations for industrial and electronics applications. It is employed as a UV-curable resin for 3D printing (SLA/DLP) and other specialty polymers to improve mechanical properties and chemical resistance of coatings and networks. Additional uses include UV-curable coatings and inks for electronics and packaging, subject to formulation limits and local regulations.
