Blocked mercaptosilane hydrolyzates as coupling agents for mineral-filled elastomer compositions

摘要

Disclosed herein are blocked mercaptosilane condensates that are useful as coupling agents in mineral filled elastomer compositions. Among the advantages in the use of these blocked mercaptosilane condensates over the use of previously described blocked mercaptosilanes are the release of less volatile organic compounds during the elastomer compounding process and lower coupling agent loading requirements.
