Abstract

A process for treating ferrous substrates for receiving a high-solids organic solvent-thinned coating by which inadvertent drippage or splashing of the dry phosphated surfaces with the iron phosphating solution does not produce blemishes, discolourations and/or surface imperfections in the final painted surface, comprises employing an aqueous iron phosphating solution devoid of any conventional inorganic oxidants or accelerating agents such as chloride or chlorate and employs an organic oxidizing agent, preferably meta nitrobenzene sulphonic acid or a salt thereof.
