Abstract
Coating compositions for metals effective to inhibit corrosion of ferrous and nonferrous metals susceptible to corrosion, said compositions comprising an inorganic-organic complex in the form of a thixotropic overbased alkaline earth metal sulfonate, particularly calcium, organic sulfonate, complexed with an alkaline earth metal, particularly calcium, carbonate; and linseed oil or a drying oil having drying properties generally similar to linseed oil, said linseed oil constituting at least 15% and, particularly, higher percentages up to about 50%, by weight of the coating compositions; and a drier, preferably of the paint drier type; and particularly advantageously also containing an epoxidized oil, particularly an epoxidized drying oil; and, also, such ingredients as mineral oils, waxes, petrolatums and resins.
