  • Applications

    N-Ethyl-1,3-propanediamine (CAS 10563-23-2) is used as a chemical intermediate for the synthesis of polyamines and other amine-containing building blocks for polyurethanes and polyamides. It also serves as a curing agent for epoxy resins in coatings and encapsulation for electronics, and can act as a crosslinking component in polyurethane/polyurea formulations for coatings and adhesives. Additionally, it may be employed as a precursor in pharmaceutical and specialty chemical synthesis, and is evaluated for use in specialty surfactants and lubricant formulations. Use is subject to local regulations and formulation limits.
