The grade GC graphite cement cures to a 100% carbonaceous bond with high electrical and thermal conductivity. It remains secure to 5432¯F (3000¯C) in a non-oxidizing atmosphere. The cement can be used to repair cracked, chipped or broken graphite trays, boats, heating elements, susceptors, dies and electrodes, as well as graphite cloth, felt, yarn, fibers, and large monolithic shapes. When used as a joint compound for furnace electrodes, it will lock the joint and lower the joint electrical resistivity. The cement is available in 1-quart, 1-gallon and 5-gallon containers.
