The invention relates to a method for coating a metal strip for use in the automotive, aircraft or aerospace industry. The strip or the strip sections produced on the basis thereof in a later step is/are first coated with at least one anticorrosive coating and then with at least one coating of a paint-like polymer-containing coating. The strip, once coated with at least one anticorrosive coating or once coated with at least one coat of a paint-like coating, is divided up in strip sections. Said coated strip sections are then formed, joined and/or coated with at least one (further) paint-like coating and/or coat of paint. The paint-like coating is achieved by coating the surface with an aqueous dispersion that contains, in addition to water, at least one UV-crosslinkable water-soluble and/or water-dispersible resin, at least one wax as the forming additive, at least one photoinitiator, and at least one corrosion inhibitor. The coating is dried and cured once it has been applied to the metal surface, thereby forming a coating that has a thickness of up to 10 &mgr;m once cured.
本发明涉及一种用于汽车、飞机或航空航天工业的
金属带材涂层方法。在后面的步骤中,带材或在其基础上生产的带材部分首先涂上至少一层防腐涂层,然后涂上至少一层含漆聚合物涂层。涂有至少一层防腐涂层或至少一层类涂料涂层的带材被分割成带材段。然后,将涂有涂层的带材段成型、连接和/或涂覆至少一层(进一步的)类油漆涂层和/或油漆层。仿油漆涂层是通过在表面涂上
水性分散体来实现的,该分散体除
水之外,还含有至少一种可紫外线交联的
水溶性和/或
水分散性
树脂、至少一种作为成型添加剂的蜡、至少一种光
引发剂和至少一种腐蚀
抑制剂。涂层涂抹到
金属表面后进行干燥和固化,从而形成固化后厚度达 10 微米的涂层。
