Description
N-Aminoethylpiperazine (CAS 140-31-8, EC 205-411-0, AEP) is an aliphatic amine also referenced under the names 1-Piperazineethanamine and 2-Piperazinoethylamine. It carries no assigned E-code and is classified under HS code 29335995.
In epoxy curing systems, AEP functions as a crosslinker by reacting with epoxide groups through its primary and secondary amine sites, building a dense polymer network that improves mechanical and chemical resistance. In water treatment formulations, its biocidal activity disrupts microbial cell membranes, making it effective for controlling bacterial growth in process water and cooling circuits.
AEP is supplied as a technical-grade liquid and is registered under REACH. Procurement teams should confirm SDS documentation and purity specifications prior to ordering, as grade requirements vary between coating and water treatment applications. Standard packaging formats for industrial supply typically include drums and intermediate bulk containers.
