    摘要： The invention relates to moisture-curable adhesive or sealant compositions comprising a) prepolymers based on aliphatic polyisocyanates and having isocyanate contents of 2 to 20 wt. %, and b) bis(dimethylaminoethyl)ether as catalyst. The compositions exhibit good storability, processability can be adjusted within wide limits and also provide rapid through-hardening.
