Abstract: To provide nitrogen-containing aromatic compounds with excellent oxygen reduction activity, metal complexes containing them, and catalysts and electrodes employing the same, the present invention provides an aromatic compound satisfying the following conditions (a) and (b): (a) It has 2 or more structures surrounded by at least 4 coordinatable nitrogen atoms (which structures may be the same or different), (b) At least one of the nitrogen atoms composing the structure is a nitrogen atom in a 6-membered nitrogen-containing heterocyclic ring.

Abstract: A silicone formulation that has a) at least one condensation-crosslinkable hydroxy- or alkoxy-terminated polydiorganosiloxane, b) at least one silane crosslinking agent or siloxane crosslinking agent for the hydroxy- or alkoxy-terminated polydiorganosiloxane and c) one or more fillers, where one filler is the main filler, the proportion by weight of which in the silicone formulation is greater than that of any other filler that may be present, and the decomposition temperature of the main filler is above 350° C., with the proviso that the proportion of the main filler in relation to the total weight of the fillers is at least 20% by weight. The silicone formulation is particularly suitable as resilient adhesive or sealant, more particularly for high-temperature applications, e.g. for producing or repairing facades, fireproof joints, windows, insulative glazing, solar installations, vehicles, white or brown goods, heaters, electronic components, or sanitary installations, or for the construction sector.

Abstract: A one- or two-component silicone formulation, preferably an RTV silicone formulation, is described that has: a) at least one poly(diorganosiloxane), b) at least one first filler having an average particle size D50 less than or equal to 0.1 ?m, c) at least one second filler having an average particle size D50 in the range of greater than 0.1 ?m to 10 ?m, and d) at least one cross-linking agent for the poly(diorganosiloxane). The constituents of the formulation can be present in one component, in the case of the one-component silicone formulation, and can be divided into two components A and B, in the case of the two-component silicone formulation. The silicone formulation is suitable in particular as an elastic adhesive for structural adhesive attachment, in particular in the facade, insulated glass, window construction, automotive, solar and construction fields. The silicone formulations have a high degree of green strength and are extraordinarily weather-resistant in the cured state.
