  • Applications

    2,2'-Ethylenedianiline (CAS 34124-14-6) is a diamine employed primarily as a curing agent for epoxy resins, enabling crosslinking and high-temperature performance in coatings, adhesives, and composite materials. It also serves as an intermediate for producing polyurethane and polyurea hardeners, and as a precursor in the synthesis of dyes, pigments, and other specialty organic chemicals. In industrial manufacturing it can be used to formulate polymeric materials and additives, including coating and ink systems, where controlled amine functionality supports curing and performance. Its use is typically subject to local regulations and formulation limits.
