Features Of ADEKA Latent Curing Agent EH-3842

  1. Highly latent at room temperature, enabling extended pot life and excellent storage stability.

  2. Activates rapidly upon thermal triggering (typically >100 °C), ensuring efficient and controllable epoxy curing.

  3. Delivers superior mechanical properties and thermal resistance in cured epoxy systems.

  4. Low volatility and minimal odor, supporting safer handling and improved workplace hygiene.

  5. Compatible with standard bisphenol-A and novolac epoxy resins without requiring co-catalysts.

Typical Applications Of ADEKA Latent Curing Agent EH-3842

  1. Prepregs for aerospace and high-performance composites.

  2. Electrical encapsulants and potting compounds for power electronics.

  3. Structural adhesives requiring precise process control and long shelf life.

  4. Coatings for metal substrates demanding high crosslink density and chemical resistance.

  5. 3D printing resins where thermal latency enables layer-by-layer deposition before final cure.
