Abstract:
The present invention relates to the use of specific inorganic Sn(IV) for the production of polyisocyanate polyaddition products from a) at least one aliphatic, cycloaliphatic, araliphatic and/or aromatic polyisocyanate, b) at least one NCO-reactive compound, c) at least one thermolatent inorganic tin-containing catalyst, d) optionally further catalysts and/or activators other than c), e) optionally fillers, pigments, additives, thickeners, antifoams and/or other auxiliary substances and additives, wherein the ratio of the weight of the tin from component c) and the weight of component a) is less than 3000 ppm when component a) is an aliphatic polyisocyanate and less than 95 ppm when component a) is an aromatic polyisocyanate, wherein as thermolatent catalysts cyclic tin compounds of formula I, II or III: wherein n>1, are used.
