POLYMER COMPOSITION FOR CORROSION PROTECTION

摘要

The invention relates to a composition for coating metal surfaces, which contains a binding component, a corrosion inhibitor polymer based on an ethylenical mono- and dicarboxylic acid and, optionally, additional ethylenical monomers, a solvent component and, optionally, cross-linked components and pigment/filling components. The invention also relates to methods for the production thereof, and to a method for coating a metal surface with the help of said composition, metal surfaces coated according to said method and to the use of the composition as a base coat, in particular, during coil coating or for atmospheric corrosion protection. After drying, the applied layer has, preferably, a thickness of at least 3,1 ?m and is thicker than a normal pre-treated layer.
