  • Patent number: 8580027
    Abstract: Fluoroalkylsilane-treated metal oxide particles and a fluoroelastomeric binder are dispersed in a fluorinated solvent with a low boiling point and applied to a substrate via spray deposition. The spray deposition process rapidly produces a conformal coating that features low surface energy and surface topography with a large range of characteristic length scales and re-entrant curvature, thereby imparting superoleophobicity. The degree of superoleophobicity is readily adjusted by means of altering the ratio of particles to binder. The choice of particle and binder result in coatings with thermal stability for thousands of hours at temperatures up to 200 degrees Celsius as well as desirable mechanical characteristics.

  • Patent number: 8415426
    Abstract: A tire is provided having a component comprised of a rubber composition containing at least one conjugated diene-based elastomer and a combination of rubber reinforcing fillers composed of rubber reinforcing carbon black, precipitated silica and granular functionalized mineral comprised of at least one of aluminum hydrate (ALOOH) and titanium dioxide. The granular mineral is functionalized by pretreatment with a coupling agent. The granular mineral fillers are pretreated with a coupling agent to promote a combination of rubber reinforcing effect for the mineral fillers and to promote a hydrophobation of the mineral fillers to promote their dispersability in the rubber composition.

  • Patent number: 8357733
    Abstract: The present invention provides a process for making silica-filled rubber masterbatch using silica hydrophobated with a trimethoxy silane coupling agent that is soluble in an alcohol-water solution containing at least about 70 wt % water. One embodiment uses a mixture of trimethoxy silanes, one or more of which react with rubber to bond the silica to the rubber, and one or more of which do not react with rubber, but do hydrophobate the silica. Hydrophobated silica is mixed with latex polymer and incorporated into rubber during coagulation of the latex, which is preferably coagulated with calcium chloride. The present invention further provides a process for making the trimethoxy silane coupling agents. Preferred trimethoxy silane coupling agents include bis-(3-trimethoxysilylpropyl)-disulfide and bis-(3-trimethoxysilylpropyl)-tetrasulfide.
