  • Publication number: 20090165913
    Abstract: Amino alkoxy-modified silsesquioxanes (amino AMS), and/or amino co-AMS compounds that also comprise a mercaptosilane or a blocked mercaptosilane, are excellent adhesives for coating plated or unplated metal wire for adherence of the wire to a rubber stock. The amino AMS and/or the amino/mercaptan co-AMS adhesives can be used with all types of rubber and there is no requirement for the use of special adhesive additives to the rubber vulcanizates, such as, but not limited to, cobalt, resins and high sulfur levels. In particular, the use of amino AMS and/or amino/mercaptan co-AMS compounds as adhesives for bonding wire to rubber also improves the adherence performance of the reinforcements to obtain sufficient bonding that is resistant to degradation over the course of time, especially resistance to thermal aging and/or thermo-oxidizing aging, in particular corrosion in the presence of water.

  • Patent number: 7544735
    Abstract: A mixture for forming a coating on a surface includes a metal alkoxide having the chemical formula Si(OR1)4, OR1 being a hydrolysable group, an organoalkoxysilane having the chemical formula R2xSiOR1(4-x), R2 being an epoxy group and x being an integer from 0 to 3 , a silica filler, and an organic acid for promoting hydrolysis and cross-linking the metal alkoxide and the organoaloxysilane. A coating on the surface is formed by depositing the mixture on the surface to form an under layer and depositing an outer layer comprising primarily a radiation activated self-cleaning material on the under layer. The radiation activated self-cleaning material can include titanium dioxide (TiO2) particles at least partially in anatase form.

  • Patent number: 7507783
    Abstract: New lithographic compositions (e.g., for use as middle layers in trilayer processes) are provided. In one embodiment, the compositions comprise an organo-silicon polymer dispersed or dissolved in a solvent system, and preferably a crosslinking agent and a catalyst. In another embodiment, the organo-silicon polymer is replaced with a polyhedral oligomeric silsesquioxane-containing polymer and/or a polyhedral oligomeric silsesquioxane. In either embodiment, the polymer and/or compound should also include —OH groups for proper cross-linking of the composition. When used as middle layers, these compositions can be applied as very thin films with a very thin layer of photoresist being applied to the top of the middle layer. Thus, the underlying bottom anti-reflective coating is still protected even though the overall stack (i.e., anti-reflective coating plus middle layer plus photoresist) is still thin compared to prior art stacks.
