Abstract: A method for producing alkali and alkaline earth alloys. It also relates to the use of the alkali and alkaline earth compositions. In order to create a novel method for producing alkali and alkaline earth alloys, it is proposed within the context of the invention that salts, hydroxides, alkoxides or oxides of alkali or alkaline earth compounds be mixed with salts, hydroxides, alkoxides or oxides of semi-metals, nonmetals or metals and then heated to at least 100° C., the salts, hydroxides, alkoxides or oxides of alkali or alkaline earth metals being present in a molar ratio of 1:1 or in excess thereof in relation to the salts, hydroxide, alkoxides or oxides of the semi-metals, nonmetals or metal.

Abstract: A process produces a coated metal strip from a semi-finished strip, in which the semi-finished strip is reeled off a coil. A corrosion protection layer is then applied to the semi-finished strip and the coated semi-finished strip is then reeled up to form a coil. The semi-finished strip is a cold-rolled strip obtained by cold rolling, cooling and recrystallization annealing. A medium containing metallic particles is applied to form the corrosion protection layer. The medium is a wet-chemical solution which is applied by spraying, dipping, squirting, flooding or rolling. The corrosion protection layer is dried on the cold-rolled strip by supplying heat at a temperature below the recrystallization annealing temperature of the cold-rolled strip after application of the medium and before reeling-up.

In order to provide a room-temperature-curing coating agent for preventing cathodic corrosion and for application as an aerosol or as brush-on paint, it is proposed that the coating agent be produced by the following method: a) Mixing 5 to 95 wt. % metal alkoxide with 5 to 95 wt. % metal pigment, b) Adding a solvent and up to 10 wt. % (relative to the amount of solid matter) of a catalyst, the catalyst being selected from the group consisting of Lewis acids, organic acids and bases, inorganic bases, functional silanes, in particular aminosilanes, inorganic acids, in particular sulphuric or phosphoric acid, phosphates or blocked phosphates, the coating agent being applied onto a metallic substrate and subsequently dried at room temperature.

Abstract: A process to produce a silane coating includes charging one or several silanes, which are not or only minimally pre-condensed, with a reactant and the thus created coating material is applied onto a substrate and then hardened. Surprisingly it has been shown that, through the reaction involving higher-molecular and only slightly pre-cross-linked silanes with a suitable reactant, a new class of coating materials can be created. The approach is advantageous insofar as restrictions with respect to pot time no longer exist and, in addition, better features of the coating material are obtained, especially a high scratch-resistance.

In order to create a vehicle paint having extremely high scratch and chemical resistance, particularly for use in multi-layer coating for OEM series coating (particularly as a clear coat or base cast), the invention proposes a method for the production of a highly abrasion-resistant vehicle paint, comprising the following steps: a. Providing at least one organic monomer, oligomer, prepolymer, or organosilane having one or more organic functional groups, or mixtures thereof; b. Saturating the functional groups described in a. by reacting them with silanes having organic side chains that contain one or more corresponding functional groups, the resultant silane having at least six SiOR groups and a molecular weight exceeding 300; c. Absorbing the resultant macro-molecular silanes in solvent, preferably protic or aprotic solvent, or mixtures thereof; d.

Abstract: The aim of the invention is to provide particles or coatings for splitting water, which are largely protected from corrosive damage. To this end, the particles or the coating consist(s) of a nucleus or a sub-layer and a shell or top layer, the nucleus or the sub-layer forming a reactive unit and consisting of a material which, on input of energy from sunlight, releases electrons capable of splitting water into hydrogen and oxygen, and the shell or top layer forming a protective unit capable of keeping the cleavage products away from the surface of the reactive unit and simultaneously having conductive fractions. Surprisingly, it has been found that corrosive damage to the reactive particles is (largely) prevented by the targeted separation of the reaction particles and the cleavage products over the kinetic range of the released electrons.
