Main purpose and application

Binder EDT-69N(M) is intended for impregnation of glass, carbon, and organic reinforcing fillers to produce prepregs and composite materials based on them. Materials based on it are widely used in aircraft construction, industry, and other critical areas.

Main application areas:
Aviation:
  • Production of carbon plastics (e.g., KMU-11E, KMU-11tr) for fuselage skin and helicopter blades.
  • Production of fiberglass (e.g., ST-69N) for radar fairings and insulators.
Space technology:
  • Heat-resistant structures operating up to +200°C.
Industry:
  • Production of honeycomb fillers and anti-corrosion coatings.
