  • Applications

    2,2'-Methylenebis(5-methylfuran) is a difunctional monomer or crosslinking agent used in epoxy resins, polyurethane systems, and UV-curable coatings and inks to enhance bonding, hardness, and chemical resistance; it is also evaluated as a precursor for furan-based polymers and resins that underpin coatings, adhesives, and industrial printing formulations. Given the furan framework, it may serve as a fragrance intermediate or odorant in perfumery, and it can function as a building block for specialty polymers intended for electronics or optical materials. Practical applications depend on local regulations and formulation limits (CAS number: 17490-66-3).
