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.
A corrosion-inhibiting composition including, as essential ingredients, (a) an inorganic-organic complex in the form of a thixotropic overbased alkaline earth metal organic sulfonate complex with an alkaline earth metal carbonate colloidally dispersed in a carrier selected from the group of volatile organic solvents, mineral oils, and mixtures of said volatile organic solvents and mineral oils, (b) a drying oil, and (c) a drier, said thixotropic overbased alkaline earth metal organic sulfonate complex with an alkaline earth metal carbonate constituting from about 10 to about 40 wt. % of said corrosion-inhibiting composition, and said drying oil constituting from about 15 to about 50 wt. % of said corrosion-inhibiting composition, said corrosion-inhibiting composition, after application in the form of a thin film on a metal surface and drying, forming a hard essentially non-oily coating.
A high solids corrosion-inhibiting composition including (a) an inorganic-organic complex in the form of a thixotropic overbased calcium organic sulfonate/calcium carbonate complex in which the organic part is an alkylbenzene in which alkyl contains from 12 to 30 carbon atoms, said complex being colloidally dispersed in a carrier selected from the group of volatile organic solvents, mineral oils, and mixtures of said volatile organic solvents and mineral oils, (b) linseed oil, (c) a drier, said thixotropic overbased calcium organic sulfonate/calcium carbonate complex constituting from about 25 to about 35 wt. % of said corrosion-inhibiting composition, and said linseed oil constituting from about 25 to about 35 wt. % of said corrosion-inhibiting composition, said high solids corrosion-inhibiting composition, after application in the form of a thin film on a metal surface and drying, forming a hard essentially non-oily coating.
