  • Applications

    2,2'-(1,2-Ethylenediyl)bis(furan) — CAS 36707-31-0 — is a difunctional furan-based building block used in polymer and resin synthesis; it serves as a difunctional monomer/crosslinker for epoxy, polyester, and phenolic systems to create networks with improved thermal and mechanical properties. It is also evaluated as a bio-based precursor for furan-containing resins and composites in industrial manufacturing. In coatings and adhesives, it can participate in reversible Diels–Alder crosslinking with dienophiles such as maleimides to form durable, heat-resistant films. It may be used in specialty polymers for electronics or optical materials due to the rigid furan rings. Use is typically guided by formulation controls and regulatory considerations.
