Polyetheramines (PEA) are polymers with a polyether backbone and amine groups at the termini, exhibiting low viscosity, long pot life, high toughness, aging resistance, and excellent waterproof properties. Their versatile applications include but are not limited to the following areas:

1. High-Performance Composites: PEA serves as a high-performance curing agent for epoxy resins, used in the production of high-strength, high-toughness composites. These composites are widely applied in the manufacturing of wind turbine blades, large-scale glass fiber composites, artificial marble, and more.

2. Polyurea Materials: PEA is a key component in polyurea materials, demonstrating excellent performance in waterproofing systems for concrete structures such as high-speed rail bridges, cross-sea bridges, dams, and large stadiums.

3. Coatings: PEA is used in the manufacture of epoxy floor coatings and water-based coatings. In the field of epoxy floor coatings, PEA is a crucial raw material for low-solvent or solvent-free epoxy coatings, reducing solvent usage and lowering system viscosity. In water-based coatings, PEA acts as a curing agent for water-based electrophoretic paints and water-based epoxy coatings, offering strong water solubility, moderate reaction speed, resistance to whitening upon air exposure, and excellent decorative effects.

4. Adhesives: PEA, as an epoxy resin curing agent, exhibits excellent toughness and fatigue resistance after full curing, finding wide application in adhesives and structural adhesives. For instance, in jewelry adhesives, PEA-crosslinked products enhance the properties of cured materials, suitable for producing artificial crystal decorations.

5. Jewelry Manufacturing: PEA has very light coloration and excellent yellowing resistance, making it suitable for jewelry manufacturing.

6. Gasoline Detergents: PEA possesses excellent cleaning, dispersing, demulsifying, corrosion inhibiting, and antioxidant properties, inhibiting the formation of deposits in automotive fuel injectors, intake valves, and combustion chambers. Compared to polyisobutylamine-based gasoline detergents, PEA not only does not generate deposits itself but also removes existing combustion chamber deposits (CCD).

7. Oil and Gas Exploration: PEA is the most effective shale inhibitor developed in the past decade and is the most environmentally friendly inhibitor in offshore oil and gas exploration. Modified PEA has excellent binding affinity with clay at both ends and can adjust the hydrophilicity of the polyether backbone through molecular design, making it soluble in water while preventing clay layer hydration when bound to clay, exhibiting superior shale inhibition performance.

8. Textile Printing and Dyeing: PEA has strong surface activity and contains primary amines that can be modified through reactions to change its hydrophilicity, making it useful as a textile printing and dyeing auxiliary.

9. Electronic Materials: PEA offers high insulation, high heat resistance, and low dielectric constant, making it suitable for manufacturing electronic materials such as electronic components and circuit boards to improve the performance and reliability of electronic products. Specific applications include electronic sealing compound curing agents, electronic encapsulation material curing agents, and more.

Furthermore, PEA is also used in rapid-curing RIM, structural adhesive curing agents, modified curing agents for polyetheramines, heavy-duty corrosion-resistant coating curing agents, and composite curing agents for fishing rods, golf clubs, tennis rackets, and other applications.

In summary, due to its excellent comprehensive properties, PEA is widely used in multiple fields and, with continuous technological advancements and market expansion, its application areas are expected to further broaden.
