| 20090214883 | CHROMIUM-FREE, THERMALLY CURABLE CORROSION PROTECTION COMPOSITION - Chromium-free, curable corrosion protection composition for primary coating of metallic substrates, which has a pH in the range from 1 to 3 and contains water and a) fluorocomplex ions of titanium and/or zirconium, b), at least one corrosion protection pigment, c) at least one organic polymer which is soluble or dispersible in water in the specified pH range and on its own in aqueous solution at a concentration of 50% by weight has a pH in the range from 1 to 3, process for treating metal strip with this composition and treated metal strip which can be obtained in this way. The organic polymer c) is preferably selected so that it contains at least one monomer selected from among acrylic acid, methacrylic acid, acrylic esters and methacrylic esters as free-radically polymerizable, ethylenically unsaturated monomers and has at least one type of functional groups selected from among epoxy, silane, hydroxy, carboxyl, phosphoric acid and phosphoric ester groups. | 08-27-2009 |
| 20090305060 | Hot Melt Adhesive for Microwave Heating - The invention relates to a hot melt adhesive, when irradiated with microwave radiation, heats up and loses its adhesive properties. The invention further relates to a process for bonding and opening package with the hot melt adhesives. The hot melt adhesive is particularly well suited for food packages. | 12-10-2009 |
| 20100112302 | MULTI COATED METAL SUBSTRATE AND METHOD FOR THE PRODUCTION THEREOF - A metal sheet, inclusive of a metal strip, having a front side and a back side, both the front side and the back side comprising a first coating having an average thickness in the range from 0.5 to 10 μm, wherein the first coating of the front side contains particles, which release divalent or multivalent metal ions upon the action of an acid, in such an amount that a self-depositing coating agent forms, upon contact with the front side, a second coating thereon, whereas this is not the case for the first coating of the back side. The first coating of the front side can be overcoated with a self-depositing coating agent. Cut edges that do not have a first coating can be covered with the self-depositing coating agent. Correspondingly coated metal sheets, as well as a method for the manufacture thereof, are furthermore within the scope of the invention. | 05-06-2010 |
| 20100113639 | METAL COMPOUNDS FOR USE AS INITIATORS - The present invention relates to initiators of the general formula {[M(L) | 05-06-2010 |
| 20100151253 | Primer Compositions for Adhesive Bonding Systems - The present invention relates to primer compositions for adhesive bonding systems. The primer compositions may be in the form of sprayable aqueous dispersions, which are shelf stable at ambient temperatures for up to three months under ambient temperature conditions, and demonstrate a cure profile of 45 to 120 minutes within the temperature range of 220° F. to 350° F. within 60 minutes of application. Significantly, the inventive primer compositions are substantially free of chromate. | 06-17-2010 |
| 20100272653 | Contrast Medium for Use in Imaging Methods - An imaging auxiliary for medical imaging methods contains stabilizer-free superparamagnetic particles such as metal oxides and metals. Preferred are γ-Fe | 10-28-2010 |
| 20100330159 | System for transporting active substances in a biological system - A stabilizer-free system for transporting active substances in a biological system of one or more active substances and magnetic particles, which is characterized in that the particles are provided with active substance(s) on at least part of their surface, is claimed. Modification of the magnetic particles is not absolutely required in this system. It can be incorporated both into aqueous and oily suspensions and into microemulsions, oil-in-water emulsions, water-in-oil emulsions and also water-in-oil-in-water emulsions. | 12-30-2010 |
| 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 |
