Features Of Huntsman Modified Amine Curing Agent Aradur 837

  1. Low-viscosity liquid formulation enabling excellent mixing and processing with epoxy resins.

  2. Fast ambient-cure capability without requiring elevated temperature post-curing.

  3. Superior flexibility and impact resistance in cured epoxy systems.

  4. Good chemical resistance, particularly to water, salts, and mild alkalis.

  5. Low exotherm profile, reducing thermal stress and minimizing risk of cracking in thick-section castings.

Typical Applications Of Huntsman Modified Amine Curing Agent Aradur 837

  1. Structural adhesives for automotive and transportation assembly.

  2. Electrical potting and encapsulation compounds for transformers and control units.

  3. Flooring and industrial coating systems requiring rapid return-to-service.

  4. Repair mortars and grouts for concrete infrastructure rehabilitation.

  5. Composite matrix resins for pultrusion and filament winding of medium-performance profiles.
