摘要:
The invention relates to a method for a preliminary metallizing treatment of galvanized or zinc alloy-coated steel surfaces or joined metallic parts that at least partly have zinc surfaces, in a surface treatment encompassing several process steps. In the disclosed method, metallic coats of especially a maximum of 100 mg/m2 of molybdenum, tungsten, cobalt, nickel, lead, tin, and/or preferably iron are produced on the treated zinc surfaces. Another embodiment of the invention relates to an uncoated or subsequently coated metallic part which has been subjected to the disclosed preliminary metallizing treatment as well as the use of such a part for making bodies during the production of automobiles, building ships, in the construction industry, and for manufacturing white products.

摘要:
A composition for coating metal surfaces based on crosslinking polyester resins as an organic constituent, which, based on its total mass, contains from 4 to 20% by weight of aluminum flakes and not more than 0.1% by weight of compounds containing isocyanate groups. The composition preferably comprises, as an organic binder, at least one hydroxylated polyester resin, preferably having a mean molar mass in the range from 2000 to 15,000, a crosslinking component for the hydroxylated polyester resin and an acidic crosslinking catalyst. A process for applying the composition to metal strip in a belt process is likewise disclosed. The layer application is adjusted within the range from 3 to 30 μm according to the end use, for which double coating may be advantageous. For example, the composition may serve as a “galvanization replacement”.
