  • Applications

    Chemical name: Benzene, 1,1'-(ethylidenebis(oxymethylene))bis-, CAS 23556-90-3; is primarily used as a chemical intermediate and crosslinking component in polymer and coating formulations, serving as a difunctional monomer or crosslinker in epoxy and polyurethane chemistries to enable network formation in coatings and adhesives; it is used in industrial manufacturing as an intermediate for the synthesis of high-performance resins and specialty polymers, and may act as a precursor for other polymeric materials and specialty chemicals; it is sometimes evaluated for use in UV-curable resin systems and acid-catalyzed resin formulations due to its bis-oxymethylene functionality; subject to local regulations and formulation limits.
