    摘要: The invention relates to compositions for the coating of substrates of matt surface appearance, based on thermoplastic and/or heat-curable resins such as PA, PP, polyesters and epoxy resins and containing one or a number of matting agents which are predominantly in the form of terephthalic acid dianilide or its substituted derivatives needles or flakes of average length of between 1 and 200 .mu.m and of aspect ratio of between 10 and 40.These compositions, generally in the form of powders, are employed for coating various substrates. The coatings are applied especially by dipping in a fluidized bed or by electrostatic spraying. The coated articles may be components of furnishing, of decoration or of construction.

    摘要: A universally applicable SiO.sub.2 -flatting agent is described, which consists of SiO.sub.2, 1 to 25% by weight polyol and optionally 1 to 25% by weight wax. The novel flatting agent is, even after lengthy storage, especially at pressure, still easily dispersible, does not lead to the formation of a hard sediment with non-thixotropic paints and lacquers, and has practically no negative effect on the thixotropic behaviour of paints and lacquers based on thixotropic polyamide-modified alkyd resins. The SiO.sub.2, polyol and wax can be brought together in a variety of ways, e.g. during the micronization of the SiO.sub.2 in a jet-mill or mechanical mill by adding polyol and wax at the same time, by spray-drying a suspension of SiO.sub.2 in an aqueous polyol solution or even before drying by adding polyol during washing or an earlier production step. It is also possible to spray-dry a suspension of SiO.sub.2, wax emulsion and polyol.
