Patent number: 7459515Abstract: Fast-curing modified siloxane compositions comprise; (1) an alkoxy- or silanol-functional silicone intermediate, (2) at least one amine reactive ingredient selected from the group consisting of acetoacetate-functional ingredients, acrylate-functional ingredients, and mixtures thereof, (3) an epoxy-functional ingredient, (4) a curing agent selected from the group consisting of amines, aminosilanes, ketimines, aldimines and mixtures thereof, and (5) water. Other ingredients useful in forming fast-curing modified siloxane compositions of this invention include silanes, organometallic catalysts, solvents, pigments, fillers and modifying agents. The above-identified ingredients are combined and reacted to form a fully cured protective film comprising a cross-linked enamine polysiloxane and/or acrylate polysiloxane chemical structure in a reduced amount of time when compared to conventional epoxy siloxane compositions.Type: GrantFiled: September 15, 2004Date of Patent: December 2, 2008Assignee: PPG Industries Ohio, Inc.Inventors: Louie Herman Gommans, Norman R. Mowrer, Haruji Sakugawa, Michael Norman Bavin, Shu Yi Chu, Karen Tisha Constable

Patent number: 7456245Abstract: This invention relates to materials which absorb and dissipate energy and/or selectively allow energy to be transmitted, methods of making same, and articles comprising such materials. In particular, polymeric materials which include polyol(s) such as, but not limited to, polyethers, polyesters, polyether/esters, acrylics, and combinations thereof, plus other formulary components such as hydroxyl-terminated polybutadienes, polyisocyanates, silicone, preferably RTV (room temperature vulcanizing) silicone, and, preferably, suitable catalysts, preferably organometallic catalysts such as DBTDL (dibutyl tin dilaurate). Included are such polymeric materials which are resilient and which resist compression and compression set while exhibiting energy absorbing properties. Optionally, additives may be functionally or cosmetically added.Type: GrantFiled: November 24, 2004Date of Patent: November 25, 2008Assignee: Battelle Memorial InstituteInventors: John D. Dunham, Joan T. Muellerleile

Publication number: 20080286583Abstract: A process for producing a composition comprising (A) a metal oxide sol containing an amine compound, such as diisopropylamine, (B) a polycondensable silicon compound having an epoxy group, such as ?-glycidoxypropyltrimethoxysilane, and (C) a curing catalyst such as tris(2,4-pentanedionato)aluminum (III), the process comprising the steps of: mixing the component (A) with the component (B) at a temperature of 10° C. or higher and lower than 40° C. for 6 hours or longer; and mixing the obtained mixture with the above component (C). There is provided a process for producing the coating composition to provide a hard coat which has excellent adhesion, scratch resistance, solvent resistance and weatherability when it is applied to the surface of a synthetic resin lens and is free from fine holes or depressions on the surface, particularly a hard coat having a high refractive index.Type: ApplicationFiled: October 6, 2005Publication date: November 20, 2008Applicant: TOKUYAMA CORPORATIONInventors: Katsuhiro Mori, Junji Momoda
