A coating composition suitable for rusty steel comprises separate components A and B.
Component A contains a polyglycidyl ether of a bisphenol having an epoxy equivalent weight between about 170 and about 200 diluted with between about 10 weight percent and about 20 weight percent of butyl glycidyl ether; an organic thixotropic agent; a liquid polyglycidyl ether of a bisphenol having an epoxy equivalent weight between about 170 and about 210; a coumarone-indene resin having a softening point between about 40°F. and about 60°F.; a urea-formaldehyde resin; leafing aluminum paste; and 2-nitropropane.
Component B contains a polyamide having a base number between about 300 and about 360; N-oleyl-1,3-propylenediamine oleate; a coumarone-indene resin having a softening point between about 40°F. and about 60°F.; microcrystalline silica; and 2,4,6-tris-(dimethylaminomethyl) phenol.
Components A and B are mixed and thinned with an aromatic hydrocarbon solvent immediately prior to application.
