Features Of Huntsman Latent Curing Agent ARADUR 9506

  1. Latent reactivity enables extended pot life at ambient temperatures, supporting efficient processing and handling.

  2. Activates rapidly upon thermal trigger (typically >120 °C), delivering fast and consistent epoxy crosslinking.

  3. Halogen-free formulation meets stringent environmental and regulatory requirements for electronics and aerospace end uses.

  4. Excellent compatibility with standard DGEBA and novolac epoxy resins ensures broad formulation flexibility.

  5. Yields cured systems with high glass transition temperature (Tg), superior thermal stability, and low dielectric loss.

Typical Applications Of Huntsman Latent Curing Agent ARADUR 9506

  1. High-performance encapsulants and glob-tops for semiconductor packaging and microelectronics.

  2. Prepregs and composite matrices in aerospace structural components requiring low outgassing and high Tg.

  3. Electrical insulation varnishes and impregnating resins for motors, generators, and transformers.

  4. Adhesives and bonding agents for demanding automotive power electronics modules.
