The siloxane epoxy coating compositions exhibit excellent film properties after curing, such as good adhesion, flexibility, weatherability, and corrosion resistance even in the absence of a chromium-containing filler. The coating compositions may be clear or may contain fillers and/or pigments. A method for manufacturing a coated metal, plastic, wood, or glass substrate using the compositions is also disclosed, as well as the coated material manufactured by the method.Type: GrantFiled: August 7, 2003Date of Patent: November 8, 2005Assignee: Polyset Company, Inc.Inventor: Ramkrishna Ghoshal

Patent number: 6958172Abstract: Hybrid films, such as those having good abrasion-resistance and defogging properties, antireflection films including it, optical products, and methods for restoring the defogging property of the hybrid films are disclosed. The hybrid films having a defogging property may be obtained through vapor deposition of an organic compound having a hydrophilic group and a reactive group along with silicon dioxide or with silicon dioxide and aluminum oxide. The antireflection film may be formed on a substrate having the hybrid film as the outermost layer opposite to the substrate. The optical product may comprise a plastic substrate and the antireflection film having the hybrid film. A method for restoring the defogging property of the hybrid film of the optical product may include washing the hybrid film.Type: GrantFiled: December 23, 2002Date of Patent: October 25, 2005Assignee: Hoya CorporationInventors: Hiroshi Shirakawa, Takeshi Mitsuishi, Kenichi Shinde

Patent number: 6949616Abstract: This invention relates to a silane-resin composition that can be obtained by at least partial hydrolytic condensation of at least the following components: (1) one or more sulfonic acid group-containing silane(s) with at least one group that can be cleaved under hydrolytic conditions, (2) one or more styryl-functionalized silane(s) and (3) one or more silane(s) that carry a nitrogen-containing heterocyclic compound, an amine group or a sulfonamide group with at least one group that can be cleaved under hydrolytic conditions, and mixing of the components before, during or after the hydrolytic condensation, as well as a process for the production of this composition. With the silane resin that is obtained, proton-conductive, organically cross-linked heteropolysiloxanes can be produced that are suitable for PEMFC in a layer or membrane form as proton-conductive systems. Their proton conductivity can be further increased by the addition of suitable liquids.Type: GrantFiled: December 20, 2002Date of Patent: September 27, 2005Inventors: Stéphane Jacob, Lothar Fröhlich, Konrad Olma, Michael Popall, Frank Kahlenberg

Patent number: 6911518Abstract: Processes have been developed for the manufacture of polyhedral oligomeric silsesquioxanes (POSS), polysilsesquioxanes, polyhedral oligomeric silicates (POS), and siloxane molecules bearing reactive ring-strained cyclic olefins (e.g. norbornenyl, cyclopentenyl, etc. functionalities). The preferred manufacturing processes employ the silation of siloxides (Si—OA, where A=H, alkaline or alkaline earth metals) with silane reagents that contain at least one reactive ring-strained cyclic olefin functionality [e.g., X3-ySi(CH3)y(CH2)2 where y=1-2 and X=OH, Cl, Br, I, alkoxide OR, acetate OOCR, peroxide OOR, amine NR2, isocyanate NCO, and R]. Alternatively, similar products can be prepared through hydrosilation reactions between silanes containing at least one silicon-hydrogen bond (Si—H) with ring-strained cyclic olefin reagents [e.g., 5-vinyl, 2 norbornene CH2?CH, cyclopentadiene]. The two processes can be effectively practiced using polymeric silsesquioxanes [RSiO1.Type: GrantFiled: December 21, 2000Date of Patent: June 28, 2005Assignee: Hybrid Plastics, LLCInventors: Joseph D.

Patent number: 6905540Abstract: The invention concerns a lubricating organo-functional silicone oil, whether or not in emulsion. The invention aims at improving oils and lubricating silicone emulsions, in terms of emulsion stability, transfer and flow of the oil in emulsion on metal surfaces, of stripping lubricating power, non-clogging of molds and paintability of molded metal articles when used for stripping. In order to achieve said aim, the inventive POS oil is functionalized with the lubricating organophilic radical W (C12-C20 alkyl) and with a radical bearing one or several adhering functions such as diacid, thiol, phosphonate, sulphonate hydroxy, hydroxyamine, amine, ether, amide and their combinations. The invention also concerns emulsions whether or not containing additives, based on said WY functionalized POS oils, the preparation of said oils and said emulsions and their uses when stripping metal articles molded in metal moulds.Type: GrantFiled: May 15, 2001Date of Patent: June 14, 2005Assignee: Rhodia ChimieInventors: Stefan Breunig, Philippe Olier
