  • Applications

    Hexamethylenediamine adipate (CAS 3323-53-3) is primarily used as a reactive building block in polymer chemistry. It serves as an intermediate in polyamide production (notably nylon-type materials) via salt formation and subsequent polycondensation; it functions as a curing agent or crosslinking component for epoxy resins used in coatings; it acts as a crosslinking or chain-extending additive for polyurethane systems employed in coatings and adhesives; and, as a diamine salt, it serves as a specialty polymer additive for engineered plastics and high-performance materials.
