Patent number: 7128977Abstract: The addition of silicone rubber fine particles to a composition comprising an organopolysiloxane having at least two alkenyl groups, an organohydrogenpolysiloxane having at least three SiH groups and a catalyst yields a composition which when coated onto any substrate, forms a coating whose surface is extremely reduced in gloss and highly uniform. Using the coating of the composition as a release sheet, synthetic resin sheets having matte surfaces can be readily manufactured.Type: GrantFiled: July 25, 2003Date of Patent: October 31, 2006Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Kenji Yamamoto, Masahiko Ogawa

Patent number: 7105614Abstract: A curable epoxy resin composition comprising at least: (A) a crystalline epoxy resin, (B) a phenol resin, and (C) a silicone resin composed of epoxy-containing organic groups and phenyl groups that define an average unit formula of this component. Component (C) is used in an amount of 0.1 to 500 parts by weight for 100 parts by weight of the sum of weights of components (A) and (B). The composition of the invention is suitable for transfer and injection molding and may find use as a curable epoxy resin composition for sealing parts of electrical and electronic devices.Type: GrantFiled: June 28, 2002Date of Patent: September 12, 2006Assignee: Dow Corning Toray Silicone Co., Ltd.Inventors: Yoshitsugu Morita, Hiroshi Ueki, Koji Nakanishi, Haruhiko Furukawa

Patent number: 7095125Abstract: A semiconductor encapsulating epoxy resin composition is provided comprising (A) an epoxy resin, (B) a phenolic resin curing agent, (C) a molybdenum compound, (D-i) an organopolysiloxane, (D-ii) an organopolysiloxane cured product, or (D-iii) a block copolymer obtained by reacting an epoxy resin or alkenyl group-bearing epoxy resin with an organohydrogenpolysiloxane, and (E) an inorganic filler. The composition has improved moldability and solder crack resistance while exhibiting high flame retardance despite the absence of halogenated epoxy resins and antimony oxide.Type: GrantFiled: July 14, 2003Date of Patent: August 22, 2006Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Shoichi Osada, Eiichi Asano, Shigeki Ino, Takayuki Aoki, Kazutoshi Tomiyoshi, Toshio Shiobara

Patent number: 7070713Abstract: A single component sag-free liquid ebonite composition having silane coupling agents selected to chemically bond and convert liquid unsaturated rubber to alkoxy functionality, to consume and scavenge moisture originally present in the mixture, and to react with sulfur during vulcanization. The single component liquid ebonite composition is moisture activated and is particularly useful for coating applications in protecting metal from corrosion and chemical attack. In some embodiments, the liquid ebonite composition having a total mass percentage of 100 is mainly composed of liquid unsaturated rubber, sulfur, a vulcanization activator, a vulcanization accelerator, a first silane, a second silane, and a third silane. With the right reactive functional group, the third silane can replace the first or second silane. In some embodiments, the liquid ebonite composition includes a catalyst, carbon black, fillers, additives, and a diluent or solvent.Type: GrantFiled: January 27, 2004Date of Patent: July 4, 2006Assignee: 3L & T, IncInventors: Rong Jong Chang, Tuan Nguyenquang, Surjit Gill

Patent number: 7067570Abstract: A one-part polysiloxane composition comprising a branched organopolysiloxane with vinyl groups bonded to silicon atoms, an organohydrogenpolysiloxane with at least two hydrogen atoms bonded to molecular chain terminal silicon atoms within each molecule, and a platinum based catalyst, together with an additional phosphite triester and an organic peroxide, is resistant to increases in viscosity, and does not gel, even on extended storage at room temperature. Even after storage, the characteristics of the cured gel product are unchanged. Accordingly, a composition of the present invention offers excellent long term storage stability at room temperature.Type: GrantFiled: December 9, 2003Date of Patent: June 27, 2006Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Masayuki Ikeno, Miyuki Tanaka, Kazuyasu Sato

Patent number: 7053141Abstract: Organosilicon compounds having alkynol groups and containing units of the formula where R3 and R2 are optionally substituted hydrocarbon radicals, R4 are divalent organic radicals, and X is a linking group are useful in addition crosslinkable compositions. The compositions exhibit long pot life and yet also exhibit excellent cure, and are useful, inter alia, in preparing molded articles and coatings.Type: GrantFiled: November 20, 2003Date of Patent: May 30, 2006Assignee: Wacker-Chemie GmbHInventor: Armin Fehn

Patent number: 7028367Abstract: A wiper blade made of a compound having a methyl vinyl silicone polymer, a filler, and a friction-reducing additive is provided. The friction-reducing additive is present in an amount from between about 5–42 weight percent, preferably 11 percent. The average particle size of the friction-reducing additive is preferably less than 6 microns, thereby permitting extrusion of the compound into the shape of a wiper blade. Polytetrafluoroethylene is preferred as a friction-reducing additive, but other substances, such as boron nitride or graphite could be used.Type: GrantFiled: December 6, 2002Date of Patent: April 18, 2006Assignee: M Management-Tex, Ltd.Inventors: Scott D.
