ABSTRACT:
Alkoxysilane-terminated, moisture-hardening polyurethanes obtained by reaction of OH-terminated diols and/or triols with diisocyanates to form NCO-terminated polyurethanes having an NCO functionality of at least 2, and reaction of some of the NCO groups with aliphatic alcohols to form a polyurethane having an NCO functionality of at least 1 and less than 2, or by reaction of the OH-terminated linear diols or triols with a mixture of mono- and diisocyanates to form NCO-terminated polyurethanes having an NCO functionality of at least 1 and less than 2, followed by a reaction of substantially all the free NCO functions of the polyurethanes obtained with aminoalkyl, mercaptoalkyl or epoxyalkyl alkoxysilanes. The polyurethanes thus obtained are particularly suitable as a basis for moisture-hardening one-component sealing compounds and adhesives.
