Features Of Huntsman Modified Aromatic Amine Curing Agent Aradur 850

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

  2. Fast-reacting at ambient temperature, delivering rapid build of mechanical properties without forced cure.

  3. Excellent chemical resistance, particularly to hydrocarbons, solvents, and weak acids after full cure.

  4. Superior adhesion to metals, composites, and concrete substrates without primer requirement.

  5. Reduced exotherm compared to standard aromatic amines, improving safety and minimizing thermal stress in thick-section casting.

Typical Applications Of Huntsman Modified Aromatic Amine Curing Agent Aradur 850

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

  2. High-performance flooring and lining systems in chemical processing plants.

  3. Electrical potting and encapsulation compounds requiring thermal stability and dielectric integrity.

  4. Marine and offshore protective coatings for steel infrastructure exposed to seawater and abrasion.

  5. Wind turbine blade bonding adhesives where low-temperature cure and toughness are critical.
