    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 oligomreric 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.
