  • Applications

    Pyromellitic glycerol dimethacrylate (CAS 148019-46-9) is primarily used as a multifunctional monomer and crosslinking agent in methacrylate/epoxy resin systems for UV-curable coatings, inks, and adhesives. Its multiple methacrylate groups enable rapid network formation, increasing hardness, chemical resistance, and dimensional stability when cured by UV light or heat. It serves as a crosslinking component in acrylic and epoxy resins to form robust networks for industrial coatings, protective layers, and adhesive formulations. It may also act as a precursor for specialty polymers and composite materials where a multifunctional, thermally stable network is advantageous. Because of its multifunctional methacrylate functionality, it is often used to tune viscosity, rigidity, and interfacial adhesion in coatings, adhesives, and other resin systems.
