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:
A sulfur-vulcanizable rubber composition is disclosed comprising at least one diene elastomer, a reinforcing filler comprising silica, and a silane coupling agent. The diene elastomer is a silane functionalized elastomer. The silane coupling agent excludes an active sulfur moiety. Also, an article of manufacture comprising said rubber composition is disclosed. Further, a non-active silica-containing rubber composition for incorporation in a tire is disclosed. The rubber composition comprises a polymer being a reaction product of a siloxyl condensation reaction between a silane functionalized diene elastomer and a non-sulfur containing silane coupling agent. Finally, a non-sulfur containing bifunctional silane coupling agent comprising at least one first end terminating group reactive with a hydroxyl group contained on silica or precipitated silica and a silane moiety contained on a diene-based elastomer is disclosed.
