A method for passivating metallic surfaces, wherein the surface is contacted with an aqueous composition comprising at least one water-soluble polymer (X) comprising acidic groups and with at least one surfactant (T) based on alkoxylated alcohols, the pH of the composition being in the range from 0.5 to 5, enables durable protection of the surface.

Method for passivating metallic surfaces with aqueous compositions comprising surfactants

Preparation for and a method of applying corrosion control coats to metallic surfaces, particularly the surfaces of metallic structures or metal constructions, the preparation comprising at least one binder system curable under atmospheric conditions, a dicarboxylic acid-olefin copolymer, and a finely divided filler, pigment or dye. Coated metallic surface obtainable by means of the method, especially the surface of metallic structures or metal constructions.

Preparation for and method of applying corrosion control coats

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

A continuous method for surface treatment of metal strips applies a finish coat having a thickness of not more than 3 &#x3bc;m, the apparatus employed for application being equipped with at least one IR sensor which faces a coated side of the strip, operates in reflection geometry, and serves to measure the coat thickness of the finish coat, with the strip running.

Continuous method for treating the surface of metal strips

The present invention relates to a method of applying atmospheric corrosion control coats to metallic surfaces, using copolymers comprising as monomeric building blocks monomers containing nitrile groups, monomers containing acidic groups, and vinylaromatic monomers. It relates, furthermore, to preparations for applying corrosion control coats.

Method for applying corrosion protection coatings to metal surfaces

The invention relates to detergent formulations for machine dishwashing which comprise copolymers having sulfonic acid and carboxylic acid functions, and to a method of using of such copolymers in machine dishwashing.

Detergent formulation for machine dishwashers

Methods for controlling atmospheric corrosion of a metallic surface including coating the metallic surface with a coating material containing at least one compound having at least one thioamide group.

Anti-corrosion coatings containing thioamide groups
