Abstract:
1. A rustproofing composition comprising: at least one heat-polymerized drying oil selected from the group consisting of polymerized oils having an iodine value of not less than 130 and which are heat-polymerized, and present in an amount ranging from 5 to 60 mass % of the rustproofing composition; at least one wax selected from the group consisting of natural waxes and synthetic waxes; and at least one rustproofing additive selected from the group consisting of sulfonates, carboxylic acid salts, fatty acid esters, amine salts, oxide paraffin salts, and oxide wax salts, wherein the wax and the rustproofing additive together are present in an amount ranging from 1 to 50 mass % of the rustproofing composition, wherein the heat-polymerized drying oil, the wax, and the rustproofing additive are dissolved or dispersed in at least one solvent selected from the group consisting of mineral oil lubricant based oils, synthetic lubricant oil based materials, liquid saturated hydrocarbon mixtures, vegetable oil based semidrying oils, and vegetable oil based nondrying oils, and wherein a nonvolatile content of the rustproofing composition at 105° C. for 3 hours is not less than 90 mass %.
