Mainly used as a new epoxy curing agent. The resin cured by Polyetheramine T-403 has excellent toughness, impact resistance and low temperature tolerance. As its exothermic peak during solidification is low, Polyetheramine T-403 can be used to cast large epoxy resin components. In addition, its low color makes the cured casting body crystal clear. Therefore, Polyetheramine T-403 is widely applied to epoxy composites, epoxy coatings, epoxy electrophoretic coatings, binders, circuit boards, sealants and artworks etc.
Polyetheramine T-403 exhibits high performance especially in strengthening wind turbine composite blade materials. Each blade of an MW-grade wind turbines weighs 5 to 6 tons itself. Coupled with large forces in different directions and temperature variations from -50℃ to 70℃, this sets a very stringent standard for blade materials. Real life applications have shown that proper epoxy resin, cured with a specific Polyetheramine T-403, fully meets the requirement for the blades. So far there are no substitutes in the curing agents of the wind power turbine composite blades.
Polyetheramine T-403 is a kind of engine fuel oil additive with excellent resistance to sedimentation. It can also be applied to surfactants.
Polyetheramine T-403 is a poly (propylene oxide) compound mainly terminated by primary amidogen.
