Abstract: The invention relates to novel compositions for fire-protection agents for materials, to a method for treating materials for protection against fire, and to the use of the compositions as fire-protection agents. More precisely, the invention relates to compositions for a fire-protection agent, such as a fire-protection paint, for materials, characterized in that ceramizing additives and volume-builders are contained as ingredients.

Abstract: During the production of moulded bodies from a nonwoven (20) which can be solidified by a binding agent (11), differences in contour arise in critical profile regions of the moulded body using known methods. This especially occurs where the profile (26) has sharp curves or where the height of the profile sharply increases. According to the invention, moulded bodies having accurate profiles are produced by subjecting the nonwoven (20) to a suction process in points, i.e. at least in the critical profile regions, in the step of the method during which die form tool is closed. The air enclosed inside die nonwoven is thereby sucked out (37) and is used to position the fibre bundles on the contour of the form tool (25, 26) in an accurate manner. This enables an accurate embodiment of the moulded body to be obtained in terms of its contour, during cooling and hardening.

Abstract: A stable, nitrogen-rich organic compound in the form of diguanidinium-5,5zotetrazolate having the empirical formula C.sub.4 H.sub.12 N.sub.16, is with a pulverulent, chemically stable oxidizer as a pyrotechnic mixture for spontaneously generating environmentally friendly, non-toxic gases.

Abstract: A binder composition for injection moulding or extrusion of metallic or cmic powders in sintering technology comprised 30 to 90% by weight PVA with an average molecular weight of 35,000 to 1,000,000 and 10 to 70% by weight PEG with an average molecular weight of 500 to 50,000 as the melt softener and processing plasticizer. The PEG can be wholly or partly replaced by prepolymeric, aliphatic polyesters of adipic acid and PEG with an average molecular weight of 2,000 to 20,000 or by hydroxy-terminated copolymers of ethylene and propylene oxide with the same average molecular weight.

Abstract: A method of joining wood material and plasstic material. An anchoring layer is applied to the area of the wood material that is to be joined to the plastic material and adhesively joined to the respective area which has a high specific surface area and with which the plastic material is joined by injection molding. The resultant composite material can be used in particular in the furniture sector and in housing construction, where low-cost and stable veneered plastic parts can be produced by the method, which can be made fire-proof by using appropriate plastic materials. Additional fields of application are the automobile industry, the construction of campers and boats, and aircraft construction. The wood material that is mainly used is veneer wood, because of the high quality of the visible surface of the composite.

Abstract: A method for the surface modification of objects made from polyvinylidene fluoride by dehydrofluorinated of the surface of the objects. The dehydrofluorination is carried out with an etching solution which, in addition to a strong basic compound and a swelling agent and/or solvent for polyvinylidene fluoride, contains an auxiliary agent for the homogenization of the etching solution. The effect of etching is supported by an adhesion promoter. High resistance to shearing and good tough-elasticity in composite structure and laminates is achieved.
