摘要： The present invention has for its object to provide a method of producing a water-base resin composition for rust-preventive coating which is suited for metal-coated steel panels, particularly galvanized steel panels, and despite the absence of chromium therein, is capable of imparting high corrosion resistance to coated metals, with the additional advantage of improved storage stability, and to a water-base resin composition as obtained by the above production method. The production technology according to the present invention is a method of producing a water-base resin composition for rust-preventive coating which comprises reacting a water-base resin composition containing, in each liter thereof, 10 to 500 g of water-dispersible silica and 0.02 to 20 g of a silane coupling agent and/or a hydrolytic condensation product thereof at a temperature of not less than 50° C. and not over the boiling temperature thereof, and the water-base resin composition as obtainable by the above production method.
