摘要： Pinhole and blister formation during autodeposition coating of galvanized steel and similar zinciferous surfaces can be greatly reduced by exposing the zinciferous surfaces to a pinhole inhibiting aqueous HF solution containing a suitable additive before using an autodeposition process itself. The most effective additives are boric acid, polyphosphonic acids, and polyethyleneimine.

摘要： A metal sheet, inclusive of a metal strip, having a front side and a back side, both the front side and the back side comprising a first coating having an average thickness in the range from 0.5 to 10 mum, wherein the first coating of the front side contains particles, which release divalent or multivalent metal ions upon the action of an acid, in such an amount that a self-depositing coating agent forms, upon contact with the front side, a second coating thereon, whereas this is not the case for the first coating of the back side. The first coating of the front side can be overcoated with a self-depositing coating agent. Cut edges that do not have a first coating can be covered with the self-depositing coating agent. Correspondingly coated metal sheets, as well as a method for the manufacture thereof, are furthermore within the scope of the invention.

摘要： The invention relates to a sheet metal, including a metal band, comprising a front and a back, both the front and the back comprising a first coating of a medium thickness within a range of 0.5 to 10 µm, the first coating of the front containing particles that release bivalent or polyvalent metal ions upon the effect of an acid in such an amount that a self-precipitating coating agent forms a second coating thereon upon contact with the front, while this is not the case for the first coating of the back. The first coating of the front may be coated with a self- precipitating coating agent. Any cutting edges comprising no first coating may be covered by the self- precipitating coating agent. The invention further relates to the sheet metals coated accordingly, and a method for the production thereof.
