Key Characteristic Reactive intermediate, epoxy curing agent, hygroscopic, corrosive Usage
N-Aminoethylpiperazine is valued for its reactivity and finds use in several key areas:
- Epoxy Resin Curing Agent: A major application where AEP acts as an effective hardener for epoxy resins used in coatings, adhesives, flooring systems, composites, and electrical encapsulation.
- Chemical Intermediate: Serves as a raw material for manufacturing:
- Asphalt Additives: Used to improve adhesion (anti-stripping agents) between aggregates and bitumen.
- Corrosion Inhibitors: Incorporated into formulations to protect metals.
- Surfactants & Chelating Agents: Used in the synthesis pathways for specialized surface-active agents.
- Lube Oil Additives: Component in certain lubricant formulations.
- Mineral Processing: Can be used as flotation agents in mining operations.
Packaging and Transportation
Our N-Aminoethylpiperazine is packaged in robust, tightly sealed containers, typically steel drums or IBC totes, suitable for corrosive liquids. Packaging ensures product integrity and safety during handling and transit. Transportation is carried out strictly following national and international regulations for the shipment of corrosive hazardous materials.
Storage
Store N-Aminoethylpiperazine in a cool, dry, well-ventilated area designated for corrosive materials. Keep away from heat sources, direct sunlight, acids, and strong oxidizing agents. Containers must be kept tightly closed to prevent absorption of moisture and carbon dioxide from the air. Storage under a nitrogen blanket is recommended to maintain purity.
