Beschreibung
Zusammenfassung:	PURPOSE:To decrease the loading of carbon black and to improve corrosion prevention characteristics by compounding an epoxy resin, carbon black and a specified amt. or graphite powder. CONSTITUTION:A black coating compsn. contg. an epoxy resin, carbon black and a graphite powder which is in the range of 1.0-5.0 pts.wt. based on 1 pt.wt. carbon black and 5 pts.wt. or less based on 100 pts.wt. solid content of the epoxy resin. As the epoxy resin, an ordinary bisphenol A type epoxy resin can be used and various modified epoxy resins can be used, too. When the loading of the graphite powder is less than 1.0 pt.wt. based on 1.0 pt.wt. carbon black, no improvement of corrosion prevention characteristics can be realized and on the other hand when it is more than 5.0 pts.wt. based on 1 pt.wt. carbon black, the hiding power becomes too small and it is not practical.
