  • Applications

    N,N-Dimethylcyclohexylamine (CAS 98-94-2) is primarily used as an amine catalyst in polyurethane foam and elastomer formulations, accelerating the isocyanate-initiated curing reactions in rigid and flexible foam production. It also serves as a chemical intermediate for synthesizing more complex amines and related derivatives. In coatings and adhesives, it typically acts as a catalyst or curing aid for polyurethane systems. Additionally, it may be used as a solvent or processing additive in organic synthesis and polymer manufacturing. Its use is formulation-specific and subject to local regulations.
