Main purpose and application

Binder EDF is used for the production of monolithic and honeycomb fiberglass structures; for structural, thermal insulation, and radio engineering parts. It is used in aircraft construction, mechanical engineering, and other industries requiring heat-resistant and chemically resistant joints.

Main application areas:
Aviation and space:
  • Production of prepregs for helicopter blades and aircraft skin.
  • Bonding honeycomb fillers in wing structures.
Industry:
  • Production of fiberglass pipes and tanks.
  • Repair of metal structures with high vibration loads.
Special purpose:
  • Sealing of electronic components under extreme conditions.
