Graphi-Bond 551-RN is a single part, phenolic-bonded, graphite and fiber-reinforced, high temperature adhesive used to bond, fill and repair carbon-carbon and graphite components and structures used in reducing atmospheres to 5400°F (2982°C).

Graphi-Bond 551-RN 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, 4.1 in/in/°F, which matches most grades of carbon and graphite, it is ideal for thermal cycling applications.

Graphi-Bond 551-RN is an easy-to-apply, dispensable adhesive that contains no asbestos or volatile organic compounds. After setting at room temperature for 1-2 hours and curing at 265°F (129°C) for 2-4 hours, it demonstrates exceptional moisture resistance and tensile-shear strength in the range of 1100 psi.
