    摘要： 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.

    摘要： The invention relates to adhesives based on aqueous dispersions and surface-deactivated isocyanate particles and to latently reactive coatings, films and powders produced from such dispersions. The adhesives are prepared from aqueous compositions containing a) dispersed polymers with isocyanate-reactive groups; b) at least one dispersed surface-deactivated aliphatic solid polyisocyanate with a softening temperature of ≧40° C.; c) one or more compounds of elements from subgroups 5 and 6 of the periodic system of elements, in which the particular element has an oxidation number of at least +4 and, d) optionally further additives and auxiliaries.
