What is Aminoethylpiperazine?
Aminoethylpiperazine (CAS 140-31-8), commonly abbreviated as AEP, is a bifunctional amine building block carrying both a primary amine and a piperazine ring.
Where is Aminoethylpiperazine used?
- Epoxy coatings and adhesives: curing agent that reacts with epoxy resins to build cross-linked networks with improved flexibility and adhesion
- Water treatment: building block for synthesizing polymeric biocides and scale inhibitors
- Polymer production: chain extender or reactive modifier influencing mechanical properties and network density
- Sealant and elastomer manufacturing: tunes cure speed in specialty formulations
- It is used for biocidal applications across several industrial sectors.
Commercial specifications
- Technical grade, purity typically 98% or higher depending on requirement
- Packaging from drums to IBC containers
