    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 present invention relates to a composition for coating metallic surfaces, comprising a binder component; a corrosion inhibitor polymer based on an ethylenically monocarboxylic and dicarboxylic acid and, if appropriate, further ethylenical monomers, a solvent component, and, if appropriate, crosslinkable components, and also pigment/filler components. The invention further relates to processes for its preparation and also to methods of coating a metallic surface using the composition, to coated metallic surfaces thus obtained, and to the use of the composition as a primer, particularly in coil coating or in atmospheric corrosion control. After drying, the applied layer preferably has a thickness of at least 3.1 μm and is therefore thicker than a typical pretreatment layer.
