  • Applications

    tert-Butyl acrylate (CAS 1663-39-4) is an acrylate monomer used to synthesize polyacrylates for coatings and paints, technical inks, and protective finishes. It also serves as a monomer for specialty polymers and plastics and acts as an intermediate in polymer synthesis to preserve the tert-butyl ester group or be converted to acrylic acid after deprotection. Practical applications include acrylic-based adhesives and coatings for industrial use, as well as electronics-related coatings or photoresists in manufacturing. These roles illustrate its function as a reactive monomer and synthesis intermediate in the chemical industry.
