Abstract

The present invention is directed to polyisocyanate compositions containing PA0 (a) at least one organic polyisocyanate and PA0 (b) at least one dissolved catalyst corresponding to the general formula ##STR1## wherein R.sup.1 and R.sup.2 may be identical or different and denote hydrogen or a methyl group, provided that R.sup.1 and R.sup.2 do not both stand for a methyl group, PA1 R.sup.3, R.sup.4 and R.sup.5 denote identical or different organic groups which are inert in isocyanate addition reactions and PA1 k, m and n represent identical or different integers with values from 1 to 5. The present invention also relates to the use of the polyisocyanate compositions as the polyisocyanate component for the production of polyisocyanate polyaddition products, especially moisture cure coating compositions or adhesives.
