Aremco Products (Valley Cottage, NY) offers Graphi-Coat, a new high temperature oxidation resistant coating. It is designed to protect graphite crucibles and fixtures used in metallurgical casting processes. Graphi-Coat 623 is a patented titanium diboride based coating that significantly inhibits the oxidation of most commercial grades of graphite to 2000 °F (1093 °C). This two-part system is a water-based, non-volatile material that is applied easily using a brush, roller, dip- or spray-processing. The coverage rate at a theoretical dry film thickness of 1 mil is 890 ft2/gal. A minimum dry film thickness of 2.5 mils is recommended.
