FEATURES
Graphi-Bond tm 669 is a single part, graphite-filled, silicate-bonded, waterborne, high temperature
adhesive used to bond, fill and repair carbon-carbon and graphite components and structures used in
reducing atmospheres to 2500 ºF (1371 ºC).
Graphi-Bond tm 669 is used typically to bond and patch carbon-carbon and graphite components such as
brushes, RF susceptors, fixtures, electrodes, crucibles, furnace parts, metal-casting dies, and continuous
casting dies. Due to its low coefficient of thermal expansion, 4.2 ppm x 10-6/ºF, matching most grades of carbon and graphite, it is ideal for thermal cycling applications.
Graphi-Bond tm 669 is an easy-to-apply, dispensable adhesive that contains no asbestos or volatile
organic compounds. It cures at room temperature for 1-2 hours followed by heating to 200 oF for 2-4
hours.
Graphi-Bond tm 669 is available from stock in pint, quart, gallon, and five-gallon pails.
