Publication number: 20030130413Abstract: 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.Type: ApplicationFiled: November 20, 2002Publication date: July 10, 2003Inventors: Bernhard Gruenewaelder, Bernhard Schoettmer, Werner Haller, Wolfgang Klauck, Birgit Ness

Patent number: 6482876Abstract: The invention relates to an agglomerate containing at least one of the following water-soluble or water-dispersible materials as a bonding base polymer: carboxylized and/or alkoxylized starch, cellulose ether and fully synthetic vinyl polymers and/or polyacrylates. The agglomerate is characterized in that it contains a blasting agent which produces a high swelling pressure, but, advantageously, does not gel. The agglomerate can have a regular geometric form or not. Its weight should be between 0.5 and 500 g. The agglomerate is used in particular in the production of lump-free paste.Type: GrantFiled: March 15, 2000Date of Patent: November 19, 2002Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Sandra Witt-Nuesslein, Werner Haller, Bernhard Schoettmer, Monika Boecker, Wolfgang Seiter, Ingo Hardacker, Heinz-Peter Hoffmann

Patent number: 6399735Abstract: A hydrophilic, high molecular weight nonionic polyurethane, characterized by solubility in water and by a specific viscosity of at least 0.4 (1% by weight solution at 20° C.) is provided. Examples of such polyurethanes are those characterized by the following structural units: a) —O(—CH2—CH2—O)n—, where n=8 to 500, and b) —CO—NH—X—NH—CO—, where X is an aliphatic or cycloaliphatic radical. Also provided are methods of using the polyurethane as an adhesive, more particularly a hotmelt adhesive or a solvent-based adhesive, for example a wallpaper adhesive and labelling adhesive, of using polyurethane as a stabilizer in the emulsion polymerization of, in particular, vinyl acetate and vinyl chloride and in the copolymerization of ethylene and vinyl acetate, and of using the polyurethane as a thickener for aqueous systems, more particularly together with nonionic surfactants.Type: GrantFiled: July 27, 1995Date of Patent: June 4, 2002Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Herbert Fischer, Winfried Emmerling, Thomas Moeller, Hermann Onusseit, Werner Haller, Bernhard Schoettmer, Bernhard Herlfterkamp, Dieter Feustel, Klaus Friedrich, Hartmut Buesching, Norbert Huebner
