Abstract: The present invention relates to a method for producing a multilayer coating on a metallic substrate, comprising, in the given order, (1) producing a polyvinyl chloride plastisol layer on the metallic substrate, comprising the application of a polyvinyl chloride plastisol material to the metallic substrate, (2) producing a thermosetting and/or thermoplastic topcoat layer directly on the polyvinyl chloride plastisol layer, comprising the application of a thermosetting and/or thermoplastic coating material directly to the polyvinyl chloride plastisol layer, wherein both the polyvinyl chloride plastisol material and the thermosetting and/or thermoplastic coating material comprise a layered double hydroxide.

Abstract: The invention relates to a method for the corrosion-inhibiting coating of metal surfaces, which in a first step involves cleaning the metal surface and optionally treating it with a pretreatment composition and in a second step involves coating the metal surface cleaned and optionally pretreated in step (1) with a primer (P) which comprises at least one binder (BM) and at least one crosslinking agent (V), and also at least one phosphorus-containing polyester component (A), (A) being an acidic esterification product of phosphonic acid, of monophosphoric acid and/or of polyphosphoric acid, and/or of the anhydrides thereof and/or of the esters thereof, with at least one polyester (B) which contains at least two hydroxyl groups.
