Features Of Huntsman Latent Curing Agent Aradur 9664-1

  1. Latent at room temperature — enables extended pot life and ambient handling without premature gelation.

  2. Activates rapidly upon thermal cure (typically 120–160 °C), delivering efficient crosslinking with epoxy resins.

  3. Halogen-free formulation — supports compliance with RoHS, REACH, and modern environmental safety standards.

  4. Excellent storage stability — remains chemically inert for ≥12 months when stored under recommended conditions.

  5. Yields high-gloss, low-color cured films with superior mechanical strength and chemical resistance.

Typical Applications Of Huntsman Latent Curing Agent Aradur 9664-1

  1. Electrical encapsulation and potting compounds for power electronics and EV battery modules.

  2. High-performance powder coatings for automotive and architectural metal substrates.

  3. Prepregs and composite matrices in aerospace and wind energy structural components.

  4. Adhesives and bonding agents requiring precise thermal activation and minimal outgassing.

  5. Structural casting resins for industrial tooling and precision engineering parts.
