Summary
This polyfunctional amine combines the properties of a surfactant with reactive amine groups, making it valuable for epoxy curing, corrosion protection, and textile applications. Its water solubility and chelating ability distinguish it from similar amine derivatives. Proper PPE (gloves, goggles) is recommended during handling due to its alkaline nature.
