High Temperature Coating prevents oxidation of graphite.
December 6, 2011 -
Based on titanium diboride, Graphi-Coat(TM) 623 inhibits oxidation of most commercial grades of graphite to 2,000°F. Two-part, water-based, non-volatile material is applied using brush, roller, dip- or spray-processing. Typically air set for 1-2 hr at ambient temperature then cured in-situ or in 10-15 min at 1,300°F, coating protects graphite crucibles and fixtures used in metallurgical casting processes as well as graphite electrodes used in arc-melting furnaces.

New Graphi-Coat 623 Prevents Oxidation Of Graphite at High Temps
Valley Cottage, NY -
SUMMARY
Graphi-Coat(TM) 623, a new high temperature oxidation resistant coating developed by Aremco Products, Inc., is now used to protect graphite crucibles and fixtures used in metallurgical casting processes from the foundry to the jewelry industries to 2000°F (1093°C).
FEATURES
Graphi-Coat(TM) 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.
Graphi-Coat(TM) is formulated with a weight and volume solids content of 78% and 58%, respectively. 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. Once applied, Graphi-Coat(TM) is typically air set for 1-2 hours at ambient temperature then cured in-situ or in 10-15 minutes at 1300°F.
In addition to coating graphite crucibles and fixtures for metallurgical processing, Graphi-Coat(TM) 623 can be used to protect graphite electrodes used in arc-melting furnaces.
Graphi-Coat(TM) 623 is available from stock in pint size containers to five-gallon drums.
