| abstract |
Disclosed is a method for coating metals, especially zinc and the alloys thereof. According to said method, the metal a) is subjected to a conversion treatment by contacting the same with a conversion solution containing at least one simple or complex salt of at least one metal M, and c) is contacted with a coating agent which contains c1) a total of 5 to 30 percent by weight of one or several aliphatic crosslinking baking urethane resins, c2) a total of 10 to 30 percent by weight of one or several crosslinking agents for component c1, and c3) 4 to 30 percent by weight of one or several anticorrosive pigments, and the coating obtained in partial step c) is hardened. The inventive method is preferably carried out as a continuous no-rinse process. The invention further relates to a metal sheet with a coating that is obtained according to the disclosed method, a shaped part made from such a metal sheet or an object that contains such a metal sheet or a shaped part therefrom, and the use of such a metal sheet, shaped part, or object in the exterior zone of buildings. |
