Publication number: 20090227724Abstract: Preparations of surface-deactivated solid isocyanates which are dispersed in finely particulate manner, with aqueous isocyanate-reactive polymer dispersions that include a) dispersed polymers having isocyanate-reactive groups, b) dispersed surface-deactivated oligomeric solid polyisocyanates, and c) at least one catalyst, where the catalyst or the totality of catalysts accelerates the reaction of the monomeric polyisocyanates which form by the thermal cleavage of the oligomeric polyisocyanates more strongly than the thermal cleavage itself. The preparations are prepared by mixing aqueous dispersions of at least one isocyanate-reactive polymer with at least one dispersed surface-deactivated oligomeric solid polyisocyanate and at least one catalyst. The preparations can be used in binders, films and powders for bonded joints, or coatings and to make a latently cross-linking adhesive layer. Substrates can be coated with layers obtainable with the above-described preparations.Type: ApplicationFiled: March 2, 2009Publication date: September 10, 2009Inventors: Otto Ganster, Jorg Buchner, Heinz-Werner Lucas, Wolfgang Henning

Patent number: 6548619Abstract: The present invention relates to a process for the production of particles from solutions or melts of heat-activatable polyurethanes by i) dissolving a compressible auxiliary agent at a pressure of between 50 and 1000 bar into a conveyable solution or melt of a heat-activatable polyurethane to obtain a mixture of polyurethane, compressible auxiliary agent and optionally solvent, ii) optionally adjusting of the temperature of the resulting mixture to a temperature of from 40° K below to 150° K above the crystallite melting point of the polyurethane, iii) expanding the mixture by means of an expansion device into a container, while adjusting the temperature in the container to at least 5° K below the softening temperature of the polyurethane to maintain the open jet particles in a form in which they do not agglomerate, and iv) separating the formed particles from the stream of decompressed compressible auxiliary agent and optionally solvent.Type: GrantFiled: August 10, 2001Date of Patent: April 15, 2003Inventors: Alexander Pross, Heinz-Werner Lucas, Horst Stepanski, Eckhardt Weidner, Marcus Petermann, Andreas Kilzer
