The alkoxy-modified silsesquioxane compounds contain an alkoxysilane group that participates in an alkoxysilane-silica reaction as a silica dispersing agent in rubber, with the release of zero to about 0.1% by weight of the rubber of volatile organic compounds (VOC), especially alcohol, during compounding and further processing. Further described are methods for making alkoxy-modified silsesquioxanes, methods for making vulcanizable rubber compounds containing alkoxy-modified silsesquioxanes, vulcanizable rubber compounds containing alkoxy-modified silsesquioxanes, and pneumatic tires comprising a component that contains alkoxy-modified silsesquioxanes.

  • Publication number: 20110017400
    Abstract: The invention is based on the discovery that addition of certain carboxylic acid derivatives of siloxanes to thermosetting adhesive compositions and die-attach pastes renders such compositions and pastes extremely resistant to resin bleed. The present invention provides siloxane-carboxylic acid compounds useful as anti-bleed additives. Also provided are adhesive compositions and pastes containing the compounds of the invention, which are particularly useful in applications that require little to no resin bleed prior to curing of the compositions (such as e.g., electronic packaging applications).
