  • Applications

    Vinyl formate (CAS 692-45-5) is a vinyl ester monomer used primarily to synthesize poly(vinyl formate) and copolymers with other vinyl monomers, supporting coatings and high-performance adhesives in the plastics and coatings industries. Polymers derived from vinyl formate can be functionalized or engineered for specialized plastic structures through the vinyl ester functionality. It also serves as an organic synthesis intermediate, enabling the introduction of formate ester functionality into molecules and subsequent transformations to create functional materials. In industrial R&D and formulations, vinyl formate is considered a feedstock for specialty polymer and adhesive systems and for developing plastic coatings and related resins.
