摘要：A method for coating metallic surfaces with aqueous compositions, wherein asilane-based aqueous composition containing at least one silane and/or a related silicon-containing compound and optionally additional components is treated further, forexample, at temperatures above 70° C., in a pretreatment step without drying thecoating, by using at least one aqueous rinse step after this pretreatment step and thenperforming an electrodeposition coating, in which at least one surfactant is added atleast in the last rinse step of the aqueous rinse steps. Coated metallic surfaces are alsodescribed.
