Polyetheramines have polyether backbones composed of propylene oxide (PO), ethylene oxide (EO), or mixtures of PO/EO. They are available in a variety of grades with differing amine functionalities and molecular weights. These products are widely used in applications such as epoxy curing agents, polyurea coating materials, resin modifiers, metalworking fluids, and fuel additives.

Product Features
Key Applications
- Epoxy Resin Applications
Wind turbine blades
Road repair materials (injection into cracks)
Various adhesives
Automotive parts, etc.
Paints
Decorative materials - Polyurea Coatings
Roads, parking lots, building floors (applied by spraying) - Resin Modifiers (e.g., for polyamide resins)
Features
- Epoxy-cured products exhibit flexibility, excellent elongation, impact resistance, and low-temperature performance.
- Their relatively low viscosity allows for easy handling and reduces solvent usage.
- The steric hindrance structure helps delay reaction, providing a moderate pot life.
- Compared to other curing agents, they offer a relatively low toxicity profile.
