摘要

Processes for coating metal substrate to protect a substrate metal corrosion, treatment of metal substrate prior to the application of polymeric coating, and,Treatment solution "a process for protecting a substrate metal corrosion comprises the steps of providing a metal substrate, and applying a treatment solution on the surface of the substrate WEtu00e1lico, in which the treatment solution comprises a aminossilano partially hydrolyzed and a inorganic compound containing fluorine.Preferably the metal substrate is selected from the group consisting of aluminum, aluminum alloys and mixtures thereof.
