    摘要: A rust preventing treatment for a metal-plated steel product which comprises treating the metal-plated steel product with an aqueous solution containing 0.01% to 10% by weight of tannic acid on the basis of the aqueous solution and 0.001% to 10% by weight of a water-soluble or water-dispersible polymer which is stable when mixed with the tannic acid to form a corrosion resistant film on the surface of the metal-plated steel product.
