The present invention relates to polyurethanes (A) being obtainable by reaction of (a) 15% to 70% by weight of di- or polyisocyanate comprising on average from 1 to 10 allophanate groups and on average from 1 to 10 C&#x2014;C double bonds per molecule, and optionally (b) 0% to 60% by weight of further di- or polyisocyanate, with (c) 5% to 50% by weight of compounds having at least two isocyanate-reactive groups, comprising at least one polycarbonate diol with a molecular weight from 500 to 3000 g/mol weight % ages being based on total polyurethane (A), with the proviso that the total is 100%.

Polyurethanes, dispersions thereof, their preparation and use

Use of dithiophosphinic acids of the general formula HSP(R)(R) and/or salts thereof for producing chrome-free, polymer-containing corrosion control layers on metallic surfaces, Rand Rindependently of one another each being organic radicals having 1 to 30 C atoms.

Use of dithiophosphinic acid and/or its salts for producing anti-corrosion coatings that are devoid of chrome

The present invention relates to silylated amino resins, to processes for preparing them, to their use, and to coating compositions comprising them.

Silylated amino resins

Method of applying corrosion control coats, especially integrated pretreatment layers or coats for atmospheric corrosion control, to metallic surfaces, using copolymers comprising as monomeric building blocks 20% to 70% by weight of monomers containing nitrogen heterocycles, 10% to 50% by weight of monomers containing acidic groups, 10% to 50% by weight of vinylaromatic monomers, and optionally 0% to 25% by weight of further monomers. Copolymers of the stated composition, and also preparations for applying corrosion control coats.

Method for the application of corrosion-resistant layers to metallic surfaces

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 &#x3bc;m and is therefore thicker than a typical pretreatment layer.

Polymer composition for corrosion protection

Process for applying integrated pretreatment layers to metallic surfaces, particularly the surfaces of coil metals, by treatment with a composition comprising at least one binder, crosslinker, a finely divided inorganic filler, and compounds containing at least two thioamide groups or containing one thioamide group and at least one functional group. Integrated pretreatment layer obtainable by the process.

Method for applying corrosion protection layers comprising thioamides to metallic surfaces
