  • Applications

    Isopropyl methacrylate (CAS 4655-34-9) is primarily used as a reactive monomer to prepare methacrylate polymers and resins for plastics and coatings; it serves as a reactive diluent in UV-curable coatings and inks to adjust viscosity and cure speed; it is a component in methacrylate-based resins for coatings and adhesives; it is used in specialty resin formulations for electronics/optical adhesive applications; and it can act as an intermediate in industrial manufacturing formulations.
