  • Applications

    1,3-Diaminopropane (CAS 109-76-2) is a versatile diamine intermediate used primarily in polymer and material manufacturing. It serves as a chain extender for polyurethanes and polyamides and also acts as a precursor for specialty chemicals in polymer synthesis. It is commonly employed as a curing agent or crosslinker for epoxy resins in coatings, adhesives, and electronic-grade materials. Additionally, it provides a building block for specialty polymers and other industrially synthesized chemicals. These applications are pursued in industrial production under standard process controls and subject to local regulations.
