摘要： The invention relates to a pasty single-component polyurethane adhesive based on at least one polyurethane pre-polymer with an NCO terminal and at least one thickener, in addition to optionally at least one additive. According to the invention, A) the polyurethane pre-polymer with an NCO terminal is substantially linear, B) the thickener is a highly disperse silicic acid in a concentration of between 2.0 and 8.0 % by weight in relation to the pre-polymer, and C) the additive constitutes less than 10 % by weight in relation to the pre-polymer. The invention thus fulfils the practical requirements for an adhesive used for construction and assembly, both in terms of fluidity and non-sag properties.

摘要： Des systèmes de conservation réversible de gaz en fonction de la pression comprennent un système triphasique qui contient un véhicule solide (I), un solvant liquide (II) et un gaz en équilibre thermodynamique entre un état de dissolution dans le solvant et un état gazeux (III). Afin d'augmenter la capacité du véhicule d'absorber du solvant ou afin de réduire le poids du véhicule à quantité égale de solvant, les systèmes décrits se caractérisent par le fait que le véhicule (I) se compose essentiellement d'un aérogel.

摘要： L'invention décrit des mastics à deux composants de polyuréthane contenant des charges à particules fines en concentration volumique pigmentaire élevée et, si on le désire, sans solvant, à base d'un composant d'isocyanate polyfonctionnel (B) et d'un composant de polyol (A) liquide à température ambiante, consistant en constituants de mélange contenant des hydroxyles réactifs à l'isocyanate avec au moins une proportion prépondérante de polyols (A1) comportant des esters et des éthers à chaîne ramifiée, contenant au moins une partie des charges à particules fines ainsi que, selon le cas, des additifs et qui est mélangé pour application avec le composant d'isocyanate (B) et appliqué comme mélange à modeler. Pour former un mastic universel présentant une excellente élasticité et une bonne étanchéité à l'eau, alliant une très bonne capacité d'adhérence à une stabilité volumique élevée, le composant de polyol (A) contient des oléopolyols comme composants de mélange supplémentaires (A2) à fonctionalité OH d'au moins 2 à 3 environ et, si on le désire, comme autres composants de mélange supplémentaires (A3), des alcools monofonctionnels à viscosité faible et très volatils à température ambiante au moins, à caractère oléophile marqué, en mélange avec le composant (A1).

摘要： The invention relates to a method for reinforcing or sealing the walls of hollow bodies. According to said method the area of a hollow body which is to be reinforced or sealed is at least partly enveloped by at least one woven fabric which is permeable to a curing outer adhesive or by a non-woven of this type, after which the woven fabric or non-woven is impregnated with an adhesive. The invention also relates to a repair kit which can be used to reinforce or seal the walls of hollow bodies. Said kit comprises at least one woven fabric or non-woven permeable to a curing adhesive with which a hollow body can be at least partly enveloped, as well as at least one curing adhesive to which the woven fabric or non-woven is permeable.

摘要： The invention relates to pourable, fine-particle dry powders based on a water-soluble and/or water-distendable combination of non-ionogenic cellulose ethers and dried redispersion polymers mixed, if desired, with other additives with and/or without adhesive force. The new dry powders are characterized by a particle structure with the closed nuclei of the non-ionogenic cellulose ethers surrounded by a sheath for the redispersion polymers to which they firmly adhere. In another embodiment, the invention relates to a method for producing these new pourable dry powders, characterized in that the non-ionogenic cellulose ethers in powder form are mixed with the aqueous polymer dispersion and the temperature of the aqueous phase is maintained at least at the cloudiness or flocculation point of the non-ionogenic cellulose ether or above. Under these conditions, the aqueous mixture of substances is spray-dried. The new composite materials are suitable for a wide range of applications as adhesives and/or binders with improved properties.

摘要： The invention concerns an aqueous dispersion adhesive based on polyvinylacetate and an addition of between 0.1 and 2.0 wt % pyrogenic silicic acid, the dispersion containing less than 5 wt % high-boiling solvents. The polyvinylacetate dispersions are preferably dispersions which produce watertight adhesion pursuant to European standard DIN EN 204. The dispersion adhesives according to the invention are characterized not only by a thixotropic creamy consistency but also by a long open time, rapid setting behaviour, and high resistance to heat. These adhesives are suitable in particular for bonding wood and wooden materials.
