Abstract
Coating oil compositions are provided which contain an oil-soluble metal petroleum sulfonate, an oxidate ester, an organic acid ester, and a hydrocarbon oil. The coating oils are highly effective for preventing rust and corrosion of both ferrous and non-ferrous metals but are particularly advantageous for application to metal sheet which is subsequently to be electrocoated. Coating oils formulated in accordance with the present invention exhibit improved electrocoat compatibility.
