Features Of Dow FORTEGRA 100 Epoxy Composite Toughener

  1. Enhances fracture toughness and impact resistance of epoxy composites without compromising glass transition temperature (Tg).

  2. Enables excellent interlaminar shear strength (ILSS) retention after hot/wet aging.

  3. Offers low viscosity and good compatibility with standard diglycidyl ether of bisphenol-A (DGEBA) and multifunctional epoxy resins.

  4. Supports solvent-free formulation and is compatible with common amine and anhydride curing agents.

  5. Designed for aerospace-qualified processing, including autoclave and out-of-autoclave (OOA) composite manufacturing.

Typical Applications Of Dow FORTEGRA 100 Epoxy Composite Toughener

  1. Aerospace primary and secondary structural components (e.g., wing skins, fuselage panels).

  2. High-performance wind turbine blade laminates requiring damage tolerance.

  3. Racing and high-end automotive carbon fiber parts subject to dynamic loading.

  4. Defense and space applications demanding certified toughened resin systems.
