Abstract: A melamine-formaldehyde resin solution having a formaldehyde/melamine ratio smaller than or equal to 1.5, at which it possesses a water compatibility ranging from 0.15 to 4.0 at 20° C., and a stability of at least 5 hours at a F/M ratio of 1.0, a stability of at least 6 hours at a F/M ratio of 1.1, a stability of at least 13 hours at a F/M ratio of 1.2, a stability of at least 24 hours at a F/M ratio of 1.3, a stability of at least 50 hours at a F/M ratio of 1.4, and a stability of at least 200 hours at a F/M ratio of 1.5, the stability of the resin solution being linearly dependent, within the range boundaries 1.0<F/M<1.1, 1.1<F/M<1.2, 1.2<F/M<1.3, 1.3<F/M<1.4, 1.4<F/M<1.5, upon the stabilities of the corresponding F/M range boundaries.

Abstract: 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 contains soluble sterically-hindered nitroxyl compounds in an aqueous aminoplast precondensate. A UV additive for aminoplast resins with several application forms is thus obtained.

Abstract: Aminoplast resins are cured using inorganic particles as curing agents. The inorganic particles have a laminated structure and include interlamellarly exchangeable cations such as alkali cations, alkaline-earth cations, aluminum cations, iron cations and/or manganese cations. The aminoplast resins may be cured to produce semi-finished products and molding materials.

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

Abstract: 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 impermeability agents, (c) dispersion agents at a concentration of 1-10 mass % in relation to the total mass of the melamine resin precondensates. The 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.

Abstract: The invention relates to a UV-resistant, thermocurable aminoplast composite consisting of lignocellulose and/or cellulose impregnated with a stabiliser and an aminoplast containing stabilisers. The invention also relates to the production and use of said composite.

Abstract: 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, aluminium 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.
