N-Aminoethylpiperazine (AEP) is a multifunctional organic compound with a wide range of uses, mainly reflected in the following aspects:

‌Polyurethane resin raw materials‌: AEP is an important raw material for the production of polyurethane resin. Polyurethane resin is widely used in construction, automobiles, aerospace and other fields.
‌Epoxy resin curing agent‌: AEP can be used as a curing agent for epoxy resin and is used to manufacture electronic components, ships, aircraft, etc. It has the characteristics of fast curing speed and good temperature resistance of the cured product.
‌Alkyd resin modifier‌: AEP can also be used as a modifier for alkyd resins, used in the manufacture of coatings, adhesives, etc.
‌Synthesis of pharmaceutical intermediates‌: In the pharmaceutical field, AEP is used as an organic raw material for the synthesis of pharmaceutical intermediates.

Other applications: AEP is also widely used in plastics, pesticides and electroplating industries.

In addition, when handling and using AEP, appropriate safety and environmental protection measures should be followed, such as avoiding contact with skin and eyes, storing in a cool, dry, and well-ventilated place, etc.

The curing conditions of aminoethylpiperazine and epoxy resin mainly include curing ratio and curing temperature and time‌.

‌Cure Ratio‌: The curing ratio between aminoethylpiperazine and epoxy resin is affected by many factors, such as the molecular weight of the epoxy resin, epoxy group content, etc. Generally speaking, for most epoxy resin systems, the reference curing ratio value is the ratio of epoxy resin to curing agent (aminoethylpiperazine) is 1:0.5-1, that is, adding 0.5-1 times of Aminoethylpiperazine‌.
‌Curing Temperature and Time‌: Specific curing temperature and time may vary due to different epoxy resin systems and curing agents. Some studies have shown that the optimal reaction conditions may be 2 hours at 60°C‌2, while some curing conditions are 3 hours at room temperature, and then 1-2 hours at 200°C‌.

In practical applications, the curing ratio and curing conditions need to be adjusted according to specific circumstances, and small batch trials are recommended to determine the optimal curing parameters‌.
