Uses

This adhesive is used to bond:

  • Graphite flexible foil to graphite rigid insulation
  • Graphite flexible foil to carbon/carbon composite
  • Graphite flexible foil to graphite/carbon felt
  • Carbon/carbon composite to graphite rigid insulation
  • Graphite to graphite
Instructions
  • Mix adhesive well before each use.
  • Apply light coating of adhesive to one or both surfaces with a paint brush or paint roller.
  • Apply weight or pressure for best bond results.
  • Cure adhesive within 24 hours.
  • Cure at approximately 350°F for 3 hours.
Special Notes
  • For best results when bonding graphite flexible foil to graphite rigid insulation use our BC501 Coating (Graphite Insulation Surface Coating) before applying BC628 Graphite Adhesive.
  • Caution - Adhesive is flammable, be careful when curing. Adhesive will cure if ignited.
  • Use isopropyl alcohol to thin if needed (caution bonding may differ when thinned).
  • Graphite fiber may be added to adhesive to produce a paste that may be used to patch graphite rigid insulation.
