New High Temperature Graphite-Phenolic Adhesive
Graphi-BondTM 551-RN, a new single-part, high temperature, graphite based adhesive system has been launched by Aremco Products Inc (Valley Cottage, NY, USA).The adhesive 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 - matching most grades of carbon and graphite at 4.1ppm x 10-6/°F - it is said to be ideal for thermal cycling applications.
It is described as an easy to apply, dispensable adhesive that contains no asbestos or volatile organic compounds. After setting at room temperature for one to two hours and curing at 130°C for two to four hours, Aremco says that the product demonstrates exceptional mechanical strength and moisture resistance.
