  • Applications

    Ethyl Methacrylate (CAS 97-63-2) is a reactive acrylic monomer used to synthesize poly(ethyl methacrylate) and methacrylate copolymers, supporting plastics and clear resin applications in the polymers sector. It is employed in coatings and inks as a monomer or reactive diluent for UV- or electron-beam-curable systems. It is used in adhesives and sealants as a polymerizable methacrylate component to improve adhesion and performance. It serves in specialty resins for electronics and optics, including protective coatings and encapsulants for devices. It also functions as an intermediate for the synthesis of other methacrylate monomers and advanced resins. Use is subject to local regulations and formulation limits.
