Patent number: 7204877Abstract: The present invention relates to a coating composition for forming an anti-reflective coating layer for a display device, comprising a fluorinated silane with low surface tension, a conductive polymer with antistatic properties, water, and a solvent. Thus, the coating film of the present invention prepared by coating the composition has high anti-reflection, excellent stain resistance to liquid-phase stains such as fingerprints and the solid-phase stains such as dust by controlling the refractive index, surface energy, and conductivity, and thus can be usefully applied to the outermost side of a display device, regardless of the type of substrates such as a Braun tube or a flat display film and the presence of other coating layers such as a hard coating layer and an anti-glare coating layer.Type: GrantFiled: April 13, 2005Date of Patent: April 17, 2007Assignee: LG Chem, Ltd.Inventors: Young-Eun Lee, Mi-Young Han, Yeong-Rae Chang, Jeong-Jin Hong, Sung-Hoon Jang

Patent number: 7202320Abstract: The invention concerns a silicone composition crosslinkable into elastomer by hydrosilylation, in the presence of carbene-based metal catalysts. The invention aims at providing a composition of that type, stable over long periods at room temperature (one day to several months), without loss of its characteristic of being heat-curable by hydrosilylation and without generating secondary isomerization or coloring reactions. The invention is characterised in that the composition comprises: a polyorganovinylsiloxane(polydimethyl)(methylvinyl) siloxane; a polyorganohydrogenosiloxane; a platinum catalyst formed by a complex of formula C3 and optionally an acetylene crosslinking inhibitor, optionally a siliceous filler. The invention also concerns novel hydrosilylation catalysts of the metal complex type of formula C3 above.Type: GrantFiled: June 3, 2002Date of Patent: April 10, 2007Assignee: Rhodia ChimieInventors: Catherine George, Delphine Blanc-Magnard, Alain Pouchelon, Sébastien Sterin

Patent number: 7169872Abstract: This invention describes novel chemical compounds whose structures are hybrids between sulfur-containing and non-sulfur-containing silanes wherein the two types of silanes are linked by siloxane bonds. The invention includes methods of preparation for the hybrid silanes as well as their use in filled rubbers as coupling agents. The hybrid silanes described are unique in that a certain amount of water in their preparation leads to superior performance in their intended application, and that they can thus be produced more efficiently and safely than coupling agents currently used in the art, from readily available hydrated raw materials.Type: GrantFiled: April 30, 2002Date of Patent: January 30, 2007Assignee: General Electric Co.Inventor: Richard W.

Patent number: 7160962Abstract: Elastomer-modified Epoxy-polysiloxane compositions of this invention are prepared by combining a silicone intermediate, with an epoxy resin, an elastomeric resinous intermediate, a polyfunctional amine, an optional organometallic catalyst, and optional fillers, pigments, and processing agents. The composition is prepared using a sufficient amount of water to promote hydrolysis of the polysiloxane and the polycondensation of the silanols produced by such hydrolysis. In its cured form, the epoxy-polysiloxane composition exists as a uniformly dispersed arrangement of linear epoxy chain fragments that are cross-linked with a continuous polysiloxane polymer chain, wherein either or both of the epoxy and/or polysiloxane polymers are elastomer modified to provide coatings and floorings having significantly improved properties of impact resistance, flexibility, crack resistance, and abrasion resistance with compared to conventional epoxy systems.Type: GrantFiled: October 27, 2003Date of Patent: January 9, 2007Assignee: Ameron International CorporationInventor: Haruji Sakugawa
