摘要： The invention relates to a method for curing aminoplast resins according to which inorganic particles, which have a laminated structure and which comprise interlamellarly exchangeable cations of the flowing type: alkali cations, alkaline-earth cations, aluminum cations, iron cations and/or manganese cations, are used as curing agents. The invention also relates to aminoplast resins cured in such a manner, to semi-finished products and to molding materials.

摘要： The invention relates to a UV additive for aminoplast resins, to a method for producing a UV additive as well as to uses thereof. Said UV additive is characterised in that it contains soluble sterically-hindered nitroxyl compounds in an aqueous aminoplast precondensate. A UV additive for aminoplast resins with several application forms is thus obtained.

摘要： The invention relates to synthetic material dispersions consisting of (a) an aqueous phase of solutions of hydrophilic melamine resin precondensates and a latent hardening catalyst in water or in mixtures of water and alcohols C1-C6, (b) an organic nanophase in the form of nanometric droplets and/or nanoparticles derived from 70-99 % of the melamine resin precondensates which are insoluble in water and etherifieds and contain hardening acid catalysts and acid impermiability agents, (c) dispersion agents at a concentration of 1-10 mass % in relation to the total mass of the melamine resin precondensates. The ratio between the hydrophilic melamine resin precondensates and the water and etherifieds-insoluble melamine resin precondensates ranges from 10:1 to 1:10, the water content in the inventive synthetic material dispersions ranging from 8 and 50 mass %. Said synthetic material dispersions are used for producing flat coated products which are externally used in the form of laminates, of coated flat carrying materials or moulded coated bodies for construction or for sports and recreation.

摘要： The invention relates to an aminotriazine condensation product, especially a melamine condensation product which is produced by reacting aminotriazine, particularly melamine, with an oxocarboxylic acid derivative. The invention also relates to the use of said aminotriazine condensation product and to a method for the production thereof. The aminotriazine condensation product thus obtained offers a wide range of possible applications by virtue of the simple accessibility thereof for derivatisations and, by virtue of the absence of formaldehyde, more health-friendly than known condensation products.
