Features Of Huntsman Modified Amine Curing Agent Aradur 943

  1. Low-viscosity liquid formulation enabling easy handling and precise metering in automated dispensing systems.

  2. Fast ambient-cure capability with excellent through-cure performance on epoxy resins, even at low temperatures (down to 10°C).

  3. Superior chemical resistance—particularly to alkalis, solvents, and moisture—after full cure.

  4. Low exotherm profile minimizes thermal stress and warpage in thick-section or thermally sensitive composites.

  5. Non-blushing chemistry ensures consistent surface appearance and reliable adhesion in humid environments.

Typical Applications Of Huntsman Modified Amine Curing Agent Aradur 943

  1. Structural adhesive formulations for aerospace composite bonding and repair.

  2. High-performance potting and encapsulation of electronic components and power modules.

  3. Wind turbine blade root joints and spar cap bonding in renewable energy applications.

  4. Industrial flooring and heavy-duty protective coatings requiring rapid return-to-service.

  5. Tooling and mold-making compounds where dimensional stability and low shrinkage are critical.
