  • Applications

    Urethane dimethacrylate (CAS 41137-60-4) is commonly used as a reactive monomer in polyurethane acrylate (PUA) resins for UV-curable coatings, inks, and sealants, enabling rapid cure and durable crosslinked films. It is a key resin matrix component in polyurethane acrylate formulations used for coatings, paints, and UV-curable adhesives, aiming to improve hardness and adhesion. In dentistry, it is used as a resin matrix for dental composites, with lower viscosity and improved mechanical properties for the composite structure. Additionally, Urethane dimethacrylate is present in UV-curable resin formulations for 3D printing (SLA/DLP) and in UV-curable adhesive systems, and can be used in electronic applications such as coatings or encapsulants. Specific applications depend on local regulations and formulation constraints.
