Abstract

Described are moisture-curing alkoxysilane-terminated polyurethanes which can be obtained by reacting polyurethane prepolymers with a mean NCO functionality of at least 1 but less than 2 with special sulfur-free alkoxysilanes, reacting with substantially all the free NCO groups. Also described is the use of these compounds as sealing and/or adhesive compositions.
