<p>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 DEG F. and about 60 DEG 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 DEG F. and about 60 DEG 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. </p> |
