  • Applications

    1,4-Butanediol diglycidyl ether (CAS number: 2425-79-8) is primarily used as a diepoxide crosslinker and reactive diluent in epoxy resins. In coatings, inks, and adhesives and sealants, it enhances mechanical properties, thermal resistance, and adhesion by incorporating into cured epoxy networks with amine hardeners. It is widely used in epoxy formulations for polymers, including composites and electronic device packaging and encapsulation. In UV-curable coatings and inks, it can serve as a reactive diluent or monomer to adjust viscosity and network density. It is also used to tailor the properties of polymer networks in specialty epoxy resins.
