Oxidation-Resistant Coating

Graphi-Coat 623™ is a new high-temperature oxidation-resistant coating used to protect graphite crucibles and fixtures used in metallurgical casting processes up to 2000°F. Graphi-Coat 623 is a patented titanium diboride-based coating that significantly inhibits the oxidation of most commercial grades of graphite. This two-part system is a water-based, non-volatile material that is easily applied. In addition to coating graphite crucibles and fixtures for metallurgical processing, Graphi-Coat 623 can be used to protect graphite electrodes used in arc-melting furnaces.
