Main purpose and application

Binder ENFB is an epoxy binder designed for impregnation of carbon and glass fillers (tapes, fabrics, threads) and production of carbon and fiberglass based on them.

Main application areas:
Aviation:
  • Production of prepregs for helicopter blades (e.g., carbon plastics KMU-4e, KMU-7t).
  • Production of fiberglass based on fabrics (e.g., T-64(VMP)-78) and rovings (e.g., RVMPN10-1200-14).
Space technology:
  • Heat-resistant structures operating at temperatures up to 160°C.
Industry:
  • Production of honeycomb fillers and anti-corrosion coatings.
