Product Detail

2-(2-aminoethylamino)ethanol, also known as curing agent 1, is a light yellow to yellow viscous liquid with an ammonia odor, and is non-irritating. Soluble in water and ethanol, easy to absorb moisture, can absorb carbon dioxide and water from the air, and good compatibility with epoxy resin. The volatility is smaller than ethylenediamine, the viscosity is slightly larger than ethylenediamine, and the toxicity is 6 to 7 times lower than ethylenediamine. Commonly used as epoxy resin curing agent, with low toxicity, room temperature curing and other characteristics.

1. Polyether amine synthesis: hydroxyethyl ethylenediamine can be used as an important raw material for the synthesis of polyether amine. Polyether amines or urea compounds can be synthesized by reacting with compounds such as ether or formaldehyde. Polyether amines are widely used in synthetic resins, adhesives, paints, coatings and other fields.

2. Metal ion chelating agent: AEEA has the characteristics of hydroxyl and amine groups, and can be used to complex metal ions. It can form stable complexes with metal ions, which expands the application range of some metal ions in chemical reactions, such as catalysis and load catalysis.

3. Corrosion inhibitor: chemical hydroxyethyl ethylenediamine can be used as a corrosion inhibitor to prevent the corrosion and oxidation of metals by forming chelating complexes with the metal surface.

4. Penetrant: hydroxyethyl ethylenediamine can be used as penetrant in some chemical reactions, which can promote the thorough mixing and diffusion of reactants in chemical reactions.
