Abstract: The invention relates to a method for controlling the thickening of aqueous, silicate-containing systems, characterized in that at least one copolymer having an average molecular weight (Mw) of at least 3000 g/mol and not more than 60000 g/mol is added to said aqueous system and that the copolymer is, essentially statistically, made of monoethylenically unsaturated monocarboxylic acids, monoethylenically unsaturated dicarboxylic acids and eventually ethylenically unsaturated comonomers. The method is also characterized in that the polymerization is carried out in the presence of 0.01 to 100 mol-%, in relation to the total amount of all COOH groups of the mono- and dicarboxylic acids, of at least one base for producing the copolymer, the indicated amounts in wt.-% each referring to the total amount of all used monomers.

Abstract: 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 µm and is thicker than a normal pre-treated layer.
