    摘要: AN ARTICLE OF MANUFACTURE IS DESCRIBED WHICH COMPRISES A CORROSI ON RESISTANT METALLIC SUBSTRATE. THE NORMALLY CORROSION-PRONE METALLIC SUBSTRATE IS RENDERED CORROSION RESISTANT BY THE APPLICATION OF ABOUT 0.05 TO ABOUT 25 GRAMS OF A HIGH MOLECULAR WEIGHT OLEFIN POLYSULFONE PER SQUARE FOOT OF METALLIC SUBSTRATE. THE SUBSTRATE CAN BE PAINTED BEFORE OR AFTER THE APPLICATION OF THE RESIN. THE RESIN IS APPLIED TO THE SUBSTRATE BY MEANS OF A LIQUID DISPERSION CONTAINING THE DISPERSED RESIN SUCH AS WATER CONTAINING A SURFACTANT OR AN ORGANIC SOLVENT.
