STABLE SILANE COMPOSITIONS ON SILICA CARRIER

摘要

The present invention discloses blends of silanes and specific silicas, characterized in that when the blend is compounded into a rubber formulation even after 4 months of storage following formation of the blend, an unexpectedly high proportion of the silane present is available as a coupling and reinforcing agent for the rubber formulation. Over 80 % and even over 90 % of the silica can be extracted or desorbed from the blend even 4 months after formation of the blend, and rubber formulation properties indicate high availability of the silane for coupling and reinforcement.
