摘要： This invention relates to an aqueous solution and a method for preparing an organic protective coating on a Cr(lll) conversion layer which is localized on (anodized) aluminium (alloy) to enhance corrosion protection. The composition is an aqueous solution which contains water, an organic film forming agent and a corrosion inhibitor, wherein the corrosion inhibitor comprises or consists of at least one 2-arylriazole. According to the method of the present invention, the composition is used for post-treating of a Cr(lll) conversion layer on (anodized) aluminium (alloy). The invention further provides a modified Cr(III) conversion coating on (anodized) aluminium (alloy), which is producible or produced with the inventive method. The modified Cr(III) conversion coating according to the invention shows excellent corrosion protection, paint adhesion and electrical resistivity.

摘要： The present invention provides a suspension and method for improving the corrosion protection of substrates which comprise or consist of steel. It has been discovered that if an organic derivative of a bentonite clay and a modified urea are added to a dispersion of flakes of Zn, Al and/or Mg, or alloys thereof, the resulting suspension demonstrates a rheological profile which is ideally suited for coating steel substrates. In fact, the inventive suspension enables coating with a high consistency of performance. The performance of the suspension is already reached after one coating process i.e. even after a dip/spin coating process is conducted only one once. In conclusion, steel substrates can be provided with a high-quality corrosion resistant coating in a more economical way compared to the prior art.
摘要翻译：本发明提供一种用于改善由钢构成或由钢构成的基材的防腐蚀性的悬浮液和方法。已经发现，如果在Zn，Al和/或Mg的薄片或其合金的分散体中加入膨润土和改性脲的有机衍生物，则所得到的悬浮液表现出理想地适用于涂层的流变曲线钢基材。事实上，本发明的悬浮液使涂层具有高的性能一致性。在一次涂布工艺之后即使在浸渍/旋涂过程仅进行一次之后，已经达到悬浮液的性能。总之，与现有技术相比，钢基材可以以更经济的方式提供高质量的耐腐蚀涂层。
