摘要：
Moisture-curable polysilylated polyether compositions contain titanium (IV) catalysts and/or zinc/amidine catalyst mixtures and are devoid of or nearly devoid of tin compounds. The titanium catalysts and zinc/amide catalyst mixtures are surprisingly found to be highly effective, even when the moisture-curable silane groups of the compositions are dialkoxysilyl groups. The moisture-cured compositions are surprisingly stable when aged at high temperatures. In addition, the compositions are surprisingly storage-stable in the uncured state, particularly when the polysilylated polyethers contain aliphatic urethane groups. The polyether compositions are also preferably devoid of aminosilane adhesion promoters.
