Solvay BR® 680-3 Polyimide Film Adhesive
Categories: Polymer; Adhesive

Material Notes: Description: BR® 680-3 paste adhesive is a radar transparent, viscous/thixotropic material supplied at 60 – 65% solids. It is intended for bonding both metallic and non-metallic sandwich structures. It is equally suitable for bonding metals and composite laminates.BR 680-3 is co-curable at temperatures up to 700°F (371°C) with various polyimide composites. Although not mandatory, BR® 680 adhesive primer may be used to seal prepared metal surfaces.

Features & Benefits:

  • 700°F (371°C) service temperature
  • Developed specifically for honeycomb sandwich bonding
  • 350°F (177°C) processing
  • Radar transparent
  • Superior thermal oxidative stability
  • Co-curable with Avimid N and other poyimide composite materials
  • Condensation-type polyimide
Applications:
  • Honeycomb sandwich construction
  • Metal-to-metal bonding
