A rustproofing composition has superior properties satisfying rustproofing quality requirements and work quality requirements for parts around tires, parts with pockets, and plate-bonded parts, and having volatile organic solvent of not more than 10 mass %. A rustproofing composition has 5 to 60 mass % of the overall composition of at least one kind of heat-polymerized drying oil in which oil having an iodine value of not less than 130 is heat-polymerized, and 1 to 50 mass % of the overall composition of at least one kind of wax selected from natural waxes and synthetic waxes, and/or at least one kind of rustproofing additive dissolved or dispersed in mineral oil type lubricant based oils, synthetic lubricant based materials or liquid saturated-hydrocarbon mixtures vegetable oil based semidrying oils, and vegetable oil based nondrying oils. In the rustproofing composition, nonvolatile content at 105&#xb0; C. for 3 hours is not less than 90 mass %.

Rustproofing composition

A rustproofing composition has superior properties satisfying rustproofing quality requirements and workability requirements for car underbodies, parts around tires, parts with pockets, plate-bonded parts or the like of car bodies, and containing volatile organic solvent of 20 mass % or less. In a rustproofing composition containing UV curable resin and photopolymerizing initiator and at least one of rustproofing oil and rustproofing wax, the content of nonvolatile component at 105&#xb0; C. for 3 hours in the rustproofing oil and rustproofing wax is 80 mass % or more, the UV curable resin and photopolymerizing initiator are dissolved or dispersed in the rustproofing oil and rustproofing wax, and the UV curable resin is contained at 0.3 to 10 weight % to the total weight of the composition.
