Abstract (en)
Water-based corrosion protector for metals consisting of a solution of polyphosphate 23%, alcohol 2% and water 73%, and a solution consisting of tallow diamine ethoxylate 5%, alcohol 2% and water 93%. The corrosion protector is preferably intended for automobiles and is used after washing by spraying the first solution in mist form on the still wet automobile for about 15 seconds and then, after a time interval, spraying the second solution. The corrosion is reduced by this treatment by more than 50% as compared to the corrosion on unprotected automobile sheet metal.
