Abstract
The object of the underlying invention consists of an acidic aqueous metal pretreatment solution that comprises amino-functional organosilanes and organophosphorus acids. These types of metal pretreatment solutions effectively reduce temporary corrosion when applied to metal surfaces and in addition confer good adhesion properties for subsequently coated organic lacquers. The invention consequently also encompasses a process for the treatment of metal substrates, especially selected from zinc and zinc-coated steel substrates, wherein metal pretreatment solutions of this invention are applied.
