摘要：A repair coating is produced on a metallic surface by coating the surface with acorrosion protecting coating, at least partially removing the corrosion protecting coatingin the area, and applying a thin corrosion protecting coating containing silicon compound.Production of a repair coating on a metallic surface comprises coating the surface with acorrosion protecting coating applied with a composition comprising pretreatmentcompositions like activating compositions, passivating compositions, phosphatingcompositions, titanium compound(s) or zirconium compound(s) or both of them
containing compositions and after-rinse-compositions, organic compositions like primers,wet-primers, welding primers, e-coats, powder coats, base-coats or clear-coats, or siliconcompound(s) containing compositions that are solutions or dispersions containing silanes,silanols, siloxanes or polysiloxanes; at least partially removing the corrosion protectingcoating in the area; and applying a thin corrosion protecting coating containing silicon
compound with a solution or dispersion containing silane, silanol, siloxane and/orpolysiloxane. An independent claim is also included for a tool for carrying out theinventive process.
