Abstract
A final rinse for a phosphatized metal surface includes a phosphoric acid solution including aluminum chlorohydrate. The aluminum chlorohydrate solution is applied at a concentration of about 100 to about 1500 ppm at a pH of 3 to about 4.5. The pH is obtained by controlling the concentration of the phosphoric acid. This is preferably used to coat previously phosphatized metal surfaces such as iron, steel, aluminum and galvanize.
