High temperature one-part graphite based adhesive. Excellent for oxidizing atmosphere. Bonds and seals graphite structures and molds in applications up to 1400°F (760°C).

Graphi-Bond 669 exhibits a dielectric strength of 105 volts per mil, torque strength of 26 ft-lbs, and coefficient of thermal expansion of 4.2 in/in/°F.

The product must be step cured at 200°F (93°C) for 2 hours. Applied in a thin coat using a brush, spatula or dispenser. The clearance between mating parts at operating temperature should be 2-8 mils (50-200 microns). Blistering may occur if the glue line is too thick or heating too rapid.
