Abstract: A blocked amine as curing aid for polymers containing isocyanate groups and having a low monomeric diisocyanate content, obtained from the reaction of at least one monomeric diisocyanate with at least one polyol in an NCO/OH ratio of at least 3/1, followed by removal of a majority of the monomeric diisocyanates by means of a suitable separation method, and to the moisture-curing polyurethane compositions obtained from this use. The use enables storage-stable, moisture-curing polyurethane compositions which can be safely handled even without special safety precautions and can be sold without hazard labeling in many countries, have good processibility and cure reliably and rapidly at ambient temperatures to give a material of high strength, elasticity and extensibility, and high stability to weathering influences. Such moisture-curing polyurethane compositions are particularly suitable as elastic sealants, adhesives or coatings, especially also for exposed outdoor applications.

Abstract: A polyetherurethane polymer containing isocyanate groups and having an NCO content in the range from 1.3% to 1.9% by weight and a monomeric diisocyanate content of not more than 0.5% by weight, obtained from the reaction of at least one monomeric aromatic diisocyanate and a polyether triol having an average OH functionality in the range from 2.2 to 2.6 and an OH number in the range from 25 to 32 mg KOH/g in an NCO/OH ratio of at least 3/1 and subsequent removal of a majority of the monomeric diisocyanates by means of a suitable separation method, and to moisture-curing polyurethane compositions having a monomeric diisocyanate content of less than 0.1% by weight, comprising said polymer.
