Abstract: Fireproofing gels based on amine salts of acid phosphates are characterised in that they comprise an aluminium component, a phosphorus component, an amine component and if appropriate water in proportions such that, at 5 to 30.degree. C. for more than 24 hours, they form a mixture which is capable of flow, and on heating to temperatures above 45.degree. C. they change into a transparent gel in less than 24 hours. In addition to other uses, such fireproofing gels are particularly suitable for the production of laminated glass constructions having a-fire protection action.

Abstract: Materials based on gypsum and organic additives are improved if they contain polyethers and, if desired, polymers. They can be used in a wide range of areas, for example as slabs in the building sector and for improving plasters, mortars, insulating materials and other construction compositions, casts and/or moulds.

Abstract: Sandwich-like lightweight shaped articles consist of a core material containing expandable graphite expanded according to the mould and if appropriate a binder, and at least one covering layer of thermoplastic material.

Abstract: An ecologically harmless process for the production of stiffening materials containing hydraulic binders, for example plaster bandages, is characterized in that a hydraulic binder is mixed in pulverulent form with a reactive binder, this mixture is applied to a sheet-like material, the sheet-like material thus coated is rolled up and the setting reaction of the reactive binder is allowed to proceed before, during and/or after the rolling-up.

Abstract: Formulations which contain a water-dispersible polymer, a metallization catalyst, if appropriate fillers, if appropriate other constituents and water are outstandingly suitable for the pretreatment of various substrate surfaces for the purpose of subsequent metallization in a currentless metallization bath.

Abstract: Formulations containing an organometallic activator, a filler, a solvent and an aqueous dispersion of a polyurethane polymer are outstandingly suitable for activation of surfaces of plastics for currentless metallisation thereof.The components of plastic activated in this way are preferably employed, after metallisation has been carried out, for shielding from electromagnetic waves.

Abstract: In a particularly advantageous process for the production of mouldings from expandable graphite, the expandable graphite is first converted into a pre-expanded form and the latter is compression moulded in a compression moulding apparatus at temperatures below 180.degree. C. to give performs. Moldings are produced from these preforms by heating in moulds to temperatures above 180.degree. C.

Abstract: An improved process for depositing strongly adhering metallic coatings on substrate surfaces by wet chemical methods by treating the surfaces with a primer before activation.The materials produced by the process are eminently suitable for the shielding of electromagnetic waves.

Abstract: Moulded articles are produced by heating expandable graphite, in which the expandable graphite is first pre-expanded at 140.degree. to 450.degree. C. until a bulk density of 30 to 500 g/l has been reached, at least 50% by volume of a mould is then filled with the graphite thus pre-expanded, and the expansion of the graphite is then completed in the mould by heating to temperatures in the range from 300.degree. to 700.degree. C.

Abstract: To produce mouldings for screening against electromagnetic radiation it is highly advantageous to use metal fibre-containing composite materials as obtained by impregnating a bundle of continuous metal filament fibres with a polymeric adhesion-promoting substance, sheathing the resulting compact precursor with a thermoplastic matrix and cutting the resulting extrudate of composite material into defined lengths.The composite materials can be used as such or together with thermoplastic granules.
