Polyetheramine Curing Agent

Polyetheramine curing agent is a low-viscosity, high-reactivity curing agent featuring a polyether backbone and terminal amine groups. It exhibits excellent flexibility, extended pot life, low whitening risk, and superior compatibility. This series of products can significantly enhance the toughness, impact resistance, and chemical resistance of cured epoxy systems, while reducing steam pressure and irritation during application. It is particularly suitable for solvent-free or low VOC formulation systems in high-performance coatings, adhesives, and composites.

Key Benefits

Low whitening risk: During the curing process, there is minimal surface fogging or whitening, resulting in high gloss and excellent transparency.
Excellent flexibility and toughness: The polyether backbone imparts excellent bending resistance and impact resistance, effectively reducing cracking.
Extended operation time and low viscosity: The long-lasting operation period facilitates large-area construction and complex casting.
Low vapor pressure and low irritation: user-friendly operation, reducing health and safety risks.
Excellent compatibility: It can be used in conjunction with various epoxy resins, fillers, and additives; suitable for aqueous or high-solid content systems.
Optional rapid curing: Certain models support rapid curing at room temperature or accelerated curing at high temperatures.

Typical Applications

Epoxy floor coatings (self-leveling, mid-coat, topcoat)
High-performance anti-corrosion coatings and heavy-duty protection
Adhesives and sealants (structural adhesives, electronic potting compounds)
Composites (carbon fiber, fiberglass pultrusion, filament winding, hand lay-up)
Polyurea spray elastomers and waterproofing materials
Polyurethane elastomers and RIM (Reaction Injection Molding)
Waterborne epoxy systems and hydrophilic functional materials
