20080279809 | COATING MATERIAL FOR METAL SURFACES HAVING ANTIADHESIVE PROPERTIES - A composition curable by polymerization, as well as a process of applying the composition and metal substrates coated therewith, the composition comprising: a) at least one metal compound which reacts before and/or during the curing of the composition by polymerization, with at least one of components b), c) or, if present, d), so that the metal is bound in the cured composition, the metal being selected from silicon, titanium, zirconium, manganese, zinc, vanadium, molybdenum and tungsten; b) at least one monomer or oligomer which contains at least one carboxyl or ester group and at least one olefinic double bond and which has no polyether chain of at least five ethylene oxide and/or propylene oxide units; c) at least one compound which contains both a polyether chain of at least five ethylene oxide and/or propylene oxide units and at least one carboxyl or ester group having at least one polymerizable double bond; and optionally d) at least one initiator for free radical and/or cationic polymerization and/or e) a biocidal active. | 11-13-2008 |
20110194914 | Bonded Adhesion of Wire-Shaped Individual Elements by Means of a Two-Layer Acrylate Resin-Based System - The present invention relates to a method for the bonded adhesion, or connection, of a plurality of wire-shaped individual elements into an arrangement, particularly into a wire band, wherein the adjacent individual elements have predetermined breaking points allowing for the mechanical removal of the individual elements. The bonded adhesion is brought about according to the invention utilizing a two-layer system on the basis of acrylate resins consisting of an inner coating (A) and of an outer coating (B), wherein the inner coating (A) has a lower hardness, than the outer coating. In a further aspect the invention also comprises arranging a plurality of wire-shaped individual elements through such a bonded connection, particularly a wire band. | 08-11-2011 |

20100081001 | POLYMERIZABLE COMPOSITION FOR COATING METALS - The present invention relates to a polymerizable composition and to a method for coating metal surfaces, in particular steel, galvanized and alloy-galvanized steel, and also aluminum and alloys thereof, as protection against corrosion. The polymerizable composition preferably contains less than 10% by weight of portions which are not incorporated in the cured coating. In a further aspect, the invention relates to the use of the claimed composition for coating workpieces consisting of the above-mentioned metals, particularly metal surfaces in blanking lines (coil coating). The present invention therefore also comprises the use of metal surfaces, coated according to the invention, for the production of “white goods” (household appliances), automobile bodies, electronic component housings, and for the building trade and the transport sector. | 04-01-2010 |
20130192995 | PRETREATMENT OF TINPLATE PRIOR TO THE COATING THEREOF WITH LACQUER - The invention relates to a method for the anti-corrosive pretreatment of tinplate, in which an anti-corrosive primer coating is applied in a single step, said primer coating effectively preventing the shiny metal surface of the pretreated tinplate from turning black when the pretreated tinplate of the invention that is provided with a topcoat is in contact with liquids releasing or containing sulfur compounds and with food containing protein. In the disclosed method, the tinplate is anodically polarized in an electrolyte containing silicates of formula M | 08-01-2013 |
20130206603 | ELECTROLYTIC FREEZING OF ZINC SURFACES - The present invention relates to a method for the metallizing pretreatment of galvanized and/or alloy-galvanized steel surfaces or joined metallic components having at least some zinc surfaces, wherein a thin surface layer of iron is deposited on the zinc surfaces from an aqueous electrolyte containing water-soluble compounds that are a source of iron cations. The method is performed at least partially or continuously under application of an electrolytic voltage, the galvanized and/or alloy-galvanized steel surfaces being connected as cathode. The aqueous electrolyte additionally contains an accelerator selected from oxo acids of the elements phosphorus, nitrogen and/or sulfur, the elements phosphorus, nitrogen and/or sulfur being present in moderate oxidation states. | 08-15-2013 |
20130299379 | MULTISTAGE PRETREATMENT OF TINPLATE PRIOR TO THE COATING THEREOF WITH LACQUER - The invention relates to a two-stage method for the anti-corrosive pretreatment of tinplate, in which an anti-corrosive primer coating is already applied in a first step, said primer coating effectively preventing the shiny metal surface of the pretreated tinplate from turning black when the pretreated tinplate of the invention that is provided with a coating lacquer is in contact with liquids containing or releasing sulfur compounds and with food containing protein. In the disclosed method, the tinplate is anodically polarized in an electrolyte containing at least one inert water-soluble salt and is then brought in contact with an acidic aqueous composition containing water-soluble inorganic compounds of the elements Zr, Ti, Hf, and/or Si. Tinplate pretreated according to the invention can be used in particular for the production of food-safe packaging such as beverage cans or tin cans. | 11-14-2013 |
