Features Of Huntsman Polyetheramine Epoxy Curing Agent D400

  1. Low-viscosity polyetheramine offering excellent flow and wetting characteristics for complex substrates.

  2. Fast-reacting aliphatic amine with reduced exotherm, enabling improved control in thick-section casting and potting.

  3. Provides superior flexibility, impact resistance, and low-temperature toughness in cured epoxy systems.

  4. Low volatility and minimal amine blush formation, supporting consistent surface quality and intercoat adhesion.

  5. Compatible with standard epoxy resins (e.g., DGEBA) without need for solvents or accelerators.

Typical Applications Of Huntsman Polyetheramine Epoxy Curing Agent D400

  1. High-performance structural adhesives for aerospace and transportation bonding.

  2. Electrical potting and encapsulation compounds requiring thermal cycling stability and dielectric integrity.

  3. Wind turbine blade bonding and repair formulations demanding fatigue resistance and environmental durability.

  4. Marine coatings and underwater repair systems where moisture tolerance and adhesion to damp surfaces are critical.

  5. Composite tooling and mandrel materials requiring dimensional stability and demoldability.
