    • The present invention is directed to a process for increasing the adhesion of a polymeric material to a metal surface, especially during the manufacture of printed circuit boards. The metal surface is contacted with an adhesion promoting composition to form a micro-roughened surface and is then contacted with an aqueous amine-formaldehyde post-dip polymer composition. The amine is preferably melamine. Thereafter polymeric material may be bonded to the treated metal surface. The amine formaldehyde polymer post-dip composition comprises an acid, a pH adjuster, and an effective amount of an amine-formaldehyde reaction product polymer. The amine-formaldehyde reaction product polymer is formed by dissolving amine in an aqueous formaldehyde solution, adding an additive selected from the group consisting of triethanolamine, ethylene glycol, and methanol, adding an acid selected from the group consisting of acetic acid and sulfuric acid, diluting the solution with water, and adjusting the pH of the solution with a pH adjuster.
    • 本发明涉及一种提高聚合物材料对金属表面的粘附性的方法,特别是在制造印刷电路板期间。 金属表面与粘合促进组合物接触以形成微粗糙表面,然后与含水胺 - 甲醛后浸渍聚合物组合物接触。 该胺优选是三聚氰胺。 此后,聚合物材料可以结合到处理的金属表面。 胺甲醛聚合物浸渍后组合物包含酸,pH调节剂和有效量的胺 - 甲醛反应产物聚合物。 胺 - 甲醛反应产物聚合物通过将胺溶解在甲醛水溶液中,加入选自三乙醇胺,乙二醇和甲醇的添加剂,加入选自乙酸和硫酸的酸, 用水稀释溶液,并用pH调节剂调节溶液的pH值。

    • A process for producing a repair coating on at least one metallic surface that is coated with at least one corrosion protection coating A applied with at least one composition selected from the group of pretreatment compositions, of organic compositions and of silicon compound(s) containing compositions, whereby the at least one corrosion protection coating A has been at least partially removed in the area Z, whereby a thin corrosion protection coating B containing at least one silicon compound is applied with a solution or dispersion containing at least one silane, at least one silanol, at least one siloxane, at least one polysiloxane or any mixture of these (="siloxane composition") on at least a part of the area Z. Optionally, a further corrosion protection coating C may be applied on the thin corrosion protection coating B generated with the siloxane composition whereby the at least one further corrosion protection coating C is generated with at least one organic composition like a primer, a wet-primer, an e-coat, a powder coat, a base-coat or a clear-coat or with at least one composition which is the same or another siloxane composition as for the thin film B.
