The invention relates to phenolate ester compounds. In order to create a new product class which is suited as a coating material, a compound is created within the scope of the invention, having a chemical structure of the following formula: [R 1 - Ph - O] a X (R 2 ) b (R 3 ) c (OR) n-a-b-c where X = Si, Ti, Zr, Mo, Mn, Cr, W, Hf, Ge, Sn, Pb, where n=4 or X= B, V, Al, Ga, In, where n=3 or X= Zn, Ni, Cu earth alkaline, where n= 2, R 1 = O-H, H, O-Y or an organic side chain, Y = an element which is different from or the same as X and has appropriate substituents, R 2 = alkyl group or functional organic side chain, R 3 = an organic side chain that is the same as or different from R 2 , Ph = aryl group, R = alkyl group, a is an integer between 1 and n; b= 0 or 1 and c= 0 or 1, and a+b+c = n. A compound is obtained, in which an aryl group is linked into an ester by way of an O-X group. Surprisingly, it was found that materials which are stable toward hydrolysis and highly stable toward chemicals are obtained by the transesterification of silanes with phenolic compounds.

The invention relates to a method for producing alkali and alkaline earth alloys. The invention also relates to the use of the alkali and alkaline earth compounds. 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, wherein the salts, hydroxides, alkoxides or oxides of alkali or alkaline earth metals are present in a molar ratio of 1:1 or in excess in relation to the salts, hydroxide, alkoxides or oxides of the semi-metals, nonmetals or metals. Surprisingly, within the context of the invention, it has been shown that, by mixing salts, hydroxides, alkoxides or oxides of alkali or alkaline earth compounds with salts, hydroxides, alkoxides or oxides of semi-metals or metals from the 3rd or 4th main group and subsequent heating, alkali or alkaline earth alloys can be produced.

The invention relates to a method for the production of a highly abrasion-resistant vehicle paint, a vehicle paint, and the use thereof. 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 provides 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 organosilanes 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 containing one or more corresponding functional groups, wherein the resulting silane has at least six SiOR groups and a molar mass of greater than 300, c. absorbing the resulting macro-molecular silanes in solvent, preferably a protic or aprotic solvent, or mixtures thereof, d. adding reaction partners, particularly acids, Lewis acids, bases or Lewis bases, e. applying the vehicle paint created in this manner onto a substrate, and f. curing the coating material.

The invention relates to a method for producing a coating material as well as the use of said coating material. The aim of the invention is to devise a method for producing a novel coating material which allows scratch-resistant coatings to be produced and can also be used as coating powder. Said aim is achieved by reacting one or more organic molecules, oligomers, or polymers comprising at least one functional group with one or more silanes comprising at least one functional organic group on an organic side chain in order to form a covalent bond between the organic molecule, oligomer, or polymer and the silane such that a polymolecular silane is obtained which can be directly cured using a catalyst. Surprisingly, reacting (optionally slightly pre-crosslinked) organically functionalized silanes, e.g. silanes having an NCO functionalization, with suitable reaction partners has shown that a novel class of compounds can be produced which can be used as a coating material, e.g. in the form of coating powders, high solid binders, or 100 percent resins.

The invention relates to a ceramic coating material comprising ceramic and/or glass-like particles. In order to produce a ceramic coating material exhibiting no volume changes or exhibiting an increase in volume during burning, the invention provides that the ceramic coating material comprises between 10 and 90 wt.-% of reactive components, selected from the group consisting of metals, metalloids, or salts, which react during sintering at temperatures of 370 to 1,500°C in a volume-compensating or volume-increasing manner with gases to form non-volatile reaction products. This results in volume compensation or a volume increase during the burning process, since the reactive components form a reaction with atmospheric oxygen or another atmosphere.

The invention relates to particles or a coating for splitting water. The aim of the invention is to provide particles or coatings for splitting water in which corrosive damage is prevented to a great extent. To achieve this, 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 that releases electrons with the input of energy from sunlight, said electrons being capable of splitting water into hydrogen and oxygen, and the shell or top layer forming a protective unit capable of holding the split products away from the surface of the reactive unit and having at the same time conductive fractions. Surprisingly, corrosive damage to the reactive particles is prevented to a great extent by the targeted separation of reaction particles and split products over the range of the released electrons.

The invention relates to a method for coating metal surfaces, whereby at least one layer of a composition is applied to the surface, said composition comprising hydrolyzates/condensates of at least one silane or a silicone resin binder and optionally a suitable solvent, and additionally containing at least one metal filler. The coating is subsequently dried and/or cured.
