  • Applications

    Chemical name: tert-Butyl methacrylate (CAS 585-07-9) is a reactive monomer used to make acrylic polymers and copolymers for coatings and inks, where the bulky tert-butyl group helps raise Tg and enhance chemical resistance; it may be used as a component in adhesive and sealant formulations to improve adhesion and solvent resistance; it serves as a building block in specialty polymers for electronics and protective coatings; and it is often evaluated as an industrial intermediate to tailor the mechanical and thermal properties of poly(methacrylates) in various manufacturing applications.
