Abstract
PURPOSE: The titled composition having improved rust preventing properties, free from whitening, prepared by incorporating a specific amount of ultrafine Al2O3 or TiO2 with a rust preventing coating composition consisting of an alkyl orthosilicate or an alkali metal silicate, and zinc powder.
CONSTITUTION: 0.05W10.0 parts by wt. preferably 0.08W0.5 parts by wt. of ultrafine Al2O3 or TiO2 powder having an average particle size of 5W40mμ and a surface area of 30W120m2/g is incorporated with a rust preventive coating composition comprising an alkyl orthosilicate or an alkali metal silicate (A) and zinc powder (B) at a weight ratio of slid content of (A) to (B) of 1:12W18 in an amount of 100 parts by wt. based on the zine powder weight.
EFFECT: Films free from cratering due to the nonuniform dissolving of zinc during the immersion in water can be obtained.
