ABSTRACT:
Described are moisture-curing sealing and/or adhesive compositions based on alkoxysilane-terminated polyurethanes and containing diurethanes as plasticizers. The diurethanes are prepared either from diol mixtures and mono-functional isocyanates, reacting with substantially all the free hydroxyl groups, or from diisocyanates and mono-functional alcohols, reacting with substantially all the free isocyanate groups. Also described is a method of preparing the moisture-curing sealing and/or adhesive compositions and their use as joint sealants.
