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 ºF (2980 ºC).
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 ppm x 10-6/ºF, 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 ºF (130 ºC) for 2-4 hours, it demonstrates exceptional moisture resistance and tensile-shear strength in the range of 1100 psi.
Graphi-Bond™ 551-RN is available from stock in pint, quart, gallon, and five-gallon pails. Please contact Aremco’s Technical Sales Department for more information about this advanced product.
