    • The invention relates to a process for the coating of surfaces of a metallic component by contacting the surfaces of the metallic component with an aqueous composition that contains predominantly organic polymeric material whereby the aqueous composition contains at least one compound each of: A) organic film-forming polymeric material(s) selected from the group consisting of ionomeric copolymers, copolymers chemically related to ionomeric copolymers showing nearly or totally the properties of ionomeric copolymers and their corresponding monomers, comonomers, oligomers, cooligomers, polymers, blockcopolymers as well as their esters, salts and derivates, which all together are constituents of at least 80 % by weight of the total organic polymeric material and whereby the total organic polymeric material has an average acid number in the range from 20 to 300, A') optionally at least one further organic film-forming polymer or their corresponding monomer(s), oligomer(s), copolymer(s), blockcopolymer(s), their derivates or any combination of them that do not belong to A) participating in the rest of the total organic polymeric material to 100 % by weight, B) optionally neutralizing agent(s), C) cross-linking agent(s) and D) water, whereby the pH of the aqueous composition is at the beginning of the coating process in the range from 6 to 10.5.
    • 本发明涉及通过使金属组分的表面与主要含有有机聚合物材料的水性组合物接触来涂覆金属组分的表面的方法,由此水性组合物含有至少一种化合物,其各自为:A)有机膜 - 形成聚合物材料,其选自离聚物共聚物,与离聚物共聚物化学相关的共聚物,其显示离聚物共聚物及其相应的单体,共聚单体,低聚物,低聚物,聚合物,嵌段共聚物及其酯的几乎或完全的性质, 盐和衍生物,它们一起是总有机聚合物材料的至少80重量%的组分,并且其中总有机聚合物材料的平均酸值为20-300,A'),任选至少另外一个 有机成膜聚合物或其相应的单体,低聚物,共聚物, Ckc聚合物,它们的衍生物或它们的任何组合,其不属于A)将总有机聚合物材料的其余部分参与到100重量%中,B)任选的中和剂,C)交联剂 和D)水,由此水性组合物的pH处于涂层过程开始时的范围为6至10.5。
