Patent number: 9758431Abstract: A process for increasing the hydrophobicity of a porous product by treating the product, or a composition providing for the product, with a water repellent material, characterized in that the porous product or a composition providing the product, is treated with an aqueous suspension of microcapsules where the microcapsules comprise a water repellent organosilicon core material selected from an organosilane, a partially condensed organosilane and a branched siloxane resin, and a shell of a silicon-based network polymer comprising silica units.Type: GrantFiled: May 2, 2013Date of Patent: September 12, 2017Assignee: Dow Corning CorporationInventors: Frederick Campeol, Fabrizio Galeone, Jean-Paul Lecomte, Leon Marteaux, Marie-Jose Sarrazin, Brett Zimmerman

Patent number: 9701590Abstract: The invention provides a water repellent composition for treating porous substrates comprising an emulsion which includes water, at least one surfactant, and a siloxane copolymer having the formula (I) wherein R is an alkyl radical having 1 to 3 carbon atoms; a has a value of from 1 to 12; R? is an alkyl radical having 8 to 12 carbon atoms, b?2; (a+b) is at least 5. This composition shows a good depth of penetration of porous substrates especially reinforced concrete and has a low Volatile Organic Content to ASTM D 5095.Type: GrantFiled: September 19, 2012Date of Patent: July 11, 2017Assignee: DOW CORNING CORPORATIONInventors: Lok Ming Li, Yihan Liu, Timothy Roggow, Marie-Jose Sarrazin, David Selley, Andreas Stammer, Paul Vandort

Patent number: 9056793Abstract: The present invention relates to hydrophobic gypsum and to a process for making gypsum hydrophobic, in particular it relates to a powdered hydrophobing additive, a hydrophobic gypsum composition and method for preparing same using granules containing organosilicon compounds as hydrophobing additives. The invention provides a granulated additive for rendering gypsum material hydrophobic, comprising a particulate carrier on which is deposited an organosilicon component, a binder polymer and an emulsifier for the organosilicon component. Such a granulated hydrophobic additive is able to provide a high initial hydrophobicity to gypsum materials to which it is applied and that the obtained hydrophobicity can last during a long period of time.Type: GrantFiled: November 27, 2013Date of Patent: June 16, 2015Assignee: Dow Corning CorporationInventors: Laurence Gallez, Jean-Paul Lecomte, Marie-Jose Sarrazin, Marc Thibaut

Publication number: 20120015108Abstract: The invention provides a composition for improving the water repellency of a substrate, like a construction substrate for example a building component. This composition contains a mixture formed by combining: water, at least one water-repellent silicon-containing compound, which is a silicone resin, an alkoxysilane or a polysiloxane, a siloxane surfactant containing an alkylpoly(ethyleneoxy)siloxane group and an alkyl siloxane group, where the alkyl group contains 1-6 carbon atoms. The composition can be used on previous treated substrates or more generally on substrates which are difficult to wet or penetrate.Type: ApplicationFiled: October 20, 2009Publication date: January 19, 2012Inventors: Marie-Jose Sarrazin, Andreas Stammer, Donald Liles, David Selley
