Abstract: Organofunctional silanes, inclusive of dimers and oligomers, are provided in which individual silanes possess both free and blocked mercaptan functionality or particular mixtures of the organofunctional silanes possess both free and blocked mercaptan functionality. The organofunctional silanes and silane mixtures are useful, inter alia, as coupling agents for elastomeric compositions, e.g., rubber formulations employed in the manufacture of tires, where they exhibit a desirable balance of low scorch and good performance properties.

Abstract: Sulfur-containing silanes described herein can serve as coupling agents for fillers in elastomer compositions used, for example, in tires, belts, hoses, shoe soles, seals, gaskets, and the like. The sulfur containing silanes advantageously reduce or eliminate the generation of volatile organic compounds (VOCs) during use.

Abstract: The invention relates to sulfur silane coupling agents containing multiple blocked mercapto groups which are in a state of reduced activity until activated. The coupling agents are advantageously used in rubber formulations, for example, for fabricating tires with low rolling resistance.

Abstract: Sulfur-containing silane and its partially to substantially complete hydrolyzate(s) are useful as additives for filled elastomeric compositions for tires and other cured rubber articles.

Abstract: The present invention relates to coating and printing ink compositions containing silylated polyether compounds comprising a hydrolysis-resistant bis-silyl hydrocarbylene group. More particularly, the silylated polyether compound comprising a bis-silyl hydrocarbylene group provides to the coating and ink compositions formulation flexibility over the entire pH range, leveling-and-flow and surface wetting, and are non-reactive with the other components of the coating and ink compositions, thereby providing long-term shelf-stability of formulated coatings and inks. These coating and ink compositions containing silylated polyether compounds do not release silicone materials and thereby provide articles treated with these coatings and ink compositions with uniform appearance and gloss.
