Abstract

PURPOSE:To give a good coating adhesive property after a long period preservation, by carrying out chemical forming treatment for iron, zinc or these alloys and applying treating solution containing a fixed quantity of compound contained trivalent chromium, organic high molecular substance and insoluble white carbon. CONSTITUTION:Phosphate chemical treatment of lead, zinc or these alloys, is carried out. Next, 20-300mg/m<2> aqueous chromate treating solution containing water-soluble inorganic chromium compound contained 20-70wt% trivalent chromium in the whole chromium, 20-1,000pts. water-soluble or water-dispersible organic high-molecular substance (for example, polyacrylic acid) in solid resin part for the 100pts. whole chromium quantity of chromium compound and also, 10- 100pts. insoluble white carbon, is applied. Content of inorganic chromium compound in the treating solution is calculated 0.05-5% in terms of the whole chromium quantity and pH is regulated at 2.0-9.0. Weak-medium alkali fat removing is carried out on occasion of using for coating after application, drying and preservation. The material can be preserved for a long period without spoiling the coating adhesive property by forming the above substrte coating.
