  • Applications

    1,10-Decanediamine (CAS 646-25-3) is primarily used as a monomer for the production of polyamides, notably nylon 1010 formed from decanediamine and sebacic acid. It also functions as a chain extender or crosslinking diamine in epoxy and polyurethane systems, improving hardness, heat resistance, and adhesion in industrial coatings, adhesives, and composites. As a key intermediate for specialty polyamides and high-performance polymers, it is commonly used in engineering plastic formulations and electronic/high-temperature applications. Its use is subject to local regulations and formulation limits.
