Abstract

PURPOSE:To form a white rust preventing film of excellent appearance and superior corrosion resistance with no coating by treating the surface of Zn or Al with a liquid based on an aq. org. high molecular cpd. and a water sol. Cr cpd., the trivalent Cr content of which is regulated, followed by drying and washing with water.
