The invention relates to a coating mixture for applying a polymeric, corrosion-preventing protective layer to a metallic base for protecting an edge area, a soldered point, a weld seam or a repair point or for sealing the seam of one or more optionally interjoined strips, metal sheets or shaped parts.

Polymeric coating mixture, process for application of this coating mixture to a metallic substrate for protection of an edge or an area, covering, substrate coated in this manner and use thereof

A process for protecting an edge area, a soldered point, a weld seam or a repair point or for sealing a seam of one or more optionally interjoined strips, metal sheets or shaped parts, containing the steps of applying a coating mixture to at least a part of a surface of a metallic substrate, applying actinic radiation, and forming a firmly adhering, ductile, corrosion-preventing coating on the substrate.

A method for coating metallic surfaces with a paint or paint-like coating prior to forming.

Method for pretreating and/or coating metallic surfaces with a paint-like coating prior to forming and use of substrates coated in this way

The invention relates to a mixture for applying a polymer, non-corrosive, electroconductive coating which can be shaped in a low-abrasive manner, to a base. Said mixture contains at least one substance A in the form of electroconductive hard particles, at least one substance B in the form of very soft or soft, inorganic, sliding, electroconductive or semiconductive particles, and/or at least one substance C in the form of metallic, soft or hard, electroconductive or semiconductive particles and/or soot, and optionally other constituents such as an anticorrosion pigment D, the sum of the parts by weight of the inorganic sliding particles B and the metallic particles and/or soot C amounting to between 0.25 and 99.5% of the parts by weight of the water-insoluble or only slightly water-soluble pigmentation S (A+B+C), and the size of the electroconductive hard particles A amounting to less than 10 ?m in relation to the particle size transfer value d. The invention also relates to a method for producing a non-corrosive, viscoplastic coating on a base, said coating containing polymer and inorganic particles, and to an electroconductive coating containing polymer and inorganic particles.

Mixture for applying a non-corrosive, polymer coating which can be shaped in a low-abrasive manner, and method for producing the same

The invention relates to a method for coating a metallic strip. The strip or optionally, the strip sections produced from said strip in the subsequent process, is/are first coated with at least one anticorrosion layer&#x2014;according to an alternative form of embodiment, this can be left out&#x2014;and then with at least one layer of a paint-like coating containing polymers. After being coated with at least one anticorrosion layer or after being coated with at least one layer of a paint-like coating, the strip is divided into strip sections. The coated strip sections are then formed, joined and/or coated with at least one (other) paint-like coating and/or paint coating. The paint-like coating is formed by coating the surface with an aqueous dispersion containing the following in addition to water: a) at least one organic film former containing at least one water-soluble or water-dispersed polymer with an acid value of 5 to 200; b) at least one inorganic compound in particle form with an average particle diameter measured on a scanning electron microscope of 0.005 to 0.3 &#x3bc;m; and c) at least one lubricant and/or at least one corrosion inhibitor. The metallic surface that is optionally coated with at least one anticorrosion layer is brought into contact with the aqueous composition and a film containing particles is formed on the metallic surface, this film then being dried and optionally also hardened, the dried and optionally, also hardened film having a layer thickness of 0.01 to 10 &#x3bc;m. The invention also relates to a corresponding aqueous composition.
