Abstract
The current invention relates to a moisture-hardening composition that contains, in addition to a silane-functional polymer with end groups of formula (I), a reaction product that can be manufactured from an amino silane with primary amino groups and an alkene that is free of silane groups. The compositions are characterized by improved expandability with concurrent high reactivity, good adhesion characteristics, and high tear strength and are suited especially for use as elastic bonding substance or sealant.
