The present invention relates to compositions comprisingnat least one polyurethane prepolymer A with isocyanate end groups, whichnmade from at least one polyisocyanate and at least one polyolnand at least one polyaldimine B, which is available from at leastna polyamine C with aliphatic primary amino groups and at leastnan aldehyde D.n n n Also disclosed is the preparation of these compositions,nand the preparation of the polyaldimine.n n n In addition, the use of these compositions asnAdhesive, sealant, coating or covering described. Furthermore to thenProcesses for gluing, sealing or coating are provided.nFinally, articles are described, their surfacenhas been contacted at least partially with such a composition.n n n The main advantage of these compositions is the lacknOdor of the compositions before, during and after their curing. |
