Temat: Graphi-Bond 669 High Temperature Graphite Adhesive

Graphi-Bond 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 °F (1371 °C).

Graphi-Bond 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/°F, matching most grades of carbon and graphite, it is ideal for thermal cycling applications.

Graphi-Bond 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 °F for 2-4 hours.
