Features Of Huntsman Latent Curing Agent Aradur 9690

  1. Latent reactivity enables extended pot life and ambient storage stability prior to thermal activation.

  2. High-temperature curing profile (typically activated above 120 °C) ensures precise process control and low exotherm during handling.

  3. Delivers excellent mechanical properties, including high glass transition temperature (Tg) and dimensional stability in cured epoxy systems.

  4. Low volatility and minimal odor support safer industrial handling and compliance with occupational health guidelines.

  5. Compatible with standard diglycidyl ether of bisphenol-A (DGEBA) and multifunctional epoxy resins.

Typical Applications Of Huntsman Latent Curing Agent Aradur 9690

  1. Aerospace composite tooling and mandrels requiring high-temperature performance and low residual stress.

  2. Electrical encapsulation and insulating components for power electronics and transformers.

  3. High-performance adhesives for structural bonding in automotive and rail transportation.

  4. Precision casting resins used in investment molding and prototyping applications.

  5. Prepregs and filament-wound composites where controlled cure kinetics and shelf-life are critical.
