  • Applications

    N,N-Dimethyl-1,3-propanediamine (CAS 109-55-7) is chiefly used as an industrial intermediate with applications across polymer and coating sectors: as a reactive curing agent and catalyst in epoxy resin formulations used in coatings, adhesives, and electronics encapsulation; as a curing agent/chain extender in polyurethane and polyurethane–urea systems; as a precursor to cationic surfactants via quaternization for specialty cleaners and surface-active formulations; as a building block for specialty polymers and coatings where bifunctional amine groups enable crosslinking; and as a platform for functional derivatives in chemical synthesis, subject to formulation constraints and local regulations.
