ABSTRACT:
A coating and method of protecting a metal substrate from corrosion by applying a thin film of a liquid composition on the substrate and heating the wet film to an elevated temperature for a period of time to dry or cure the film and thereby adhere a protective coating to the substrate without the maximum temperature of the substrate exceeding about 500.degree. F. and preferably 450.degree. F. The composition contains a primary corrosion inhibitor of powdered metal dispersed in a bonding material of linear epoxy or phenoxy resin and a vehicle of active and inactive organic solvents. Preferably, the composition also includes secondary corrosion inhibiting resins, a thioxotropic material, a hygroscopic material, a powdered metal suspension agent, and a material to neutralize the acidity of the linear epoxy or phenoxy resin.
