摘要:
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.
摘要:
The present invention relates to a composition comprising at least one moisture-reactive silane-functional polymer which is liquid at room temperature, and at least one silane-functional polyester. Such compositions are suitable especially as moisture-curing compositions which are suitable as adhesives, sealants or coatings and have improved initial strengths.

摘要:
The present invention relates to silane-functional polyesters obtainable from the reaction of a room temperature solid polyester with an isocyanatosilane, which are used as a constituent in moisture-curing compositions such as adhesives, sealants or coatings based on silane-terminated polymers. By virtue of the use of inventive silane-functional polyesters, it is possible in particular to provide adhesives with a high initial strength.
