20080255289 | Dried Emulsion, Method for the Production Thereof, and Its Uses - The invention relates to a dried emulsion. In particular, the invention relates to a dried emulsion containing a liquid hydrophobic phase and a water-soluble or water-dispersible polymeric matrix whose hydrophobic phase content is high. The invention also relates to a method for producing the dried emulsion and to uses of this emulsion. The utilized water-soluble matrix contains block copolymers. | 10-16-2008 |
20080293876 | Use of a crosslinkable silicone-based inverse emulsion for producing "breathable waterproof" coatings - Silicone coating on various soft supports, for instance textiles, made of synthetic polymers (polyamide, polyester) provides an efficient method for producing water impermeable and water permeable coatings, on soft supports, said method enabling to improve permeability to water vapor of the silicones while preserving impermeability to water. The inventive method enabling this consists mainly in: coating one of the surfaces of the support with a film formed by an invert water-in-oil silicone emulsion comprising a continuous oily silicone phase phi s, crosslinkable into elastomer and including a polyorganosiloxane (POS) A crosslinkable by addition polymerization, by cationic process or free-radical process; optionally a crosslinking organosilicon compound B; and optionally at least a catalyst C; an aqueous phase phi a; a stabilizing agent; and in ensuring crosslinking of the silicone phase phi s and elimination of water. The invention also concerns water impermeable and water vapor permeable soft polyamide or polyester substrates obtained by using an invert water-in-oil silicone emulsion. | 11-27-2008 |
20090053436 | SILOXANE-BASED COMPOSITION, WHICH DOES NOT EMIT HYDROGEN, INTENDED FOR MOLDING/MOLD-RELEASE OF PNEUMATIC TIRES - The present invention relates to a composition I, in the form of an oil-in-water emulsion, based on siloxane and which does not emit hydrogen, comprising:

20090137698 | AQUEOUS SILICONE DISPERSIONS, FORMULATIONS, ESPECIALLY PAINT FORMULATIONS, CONTAINING THEM AND ONE OF THEIR METHODS OF PREPARATION - The invention relates to an aqueous silicone dispersion, containing one or more polyorganosiloxanes (POSs) intended to be crosslinked or having been crosslinked by elimination of water or alcohol, according to a polycondensation mechanism. The present invention also relates to methods for preparing aqueous silicone emulsions and dispersions. | 05-28-2009 |
20100078104 | Siloxane-based lubricating compositions that release no hydrogen - Lubricating compositions, in the form of oil-in-water emulsions, are based on a siloxane and do not release hydrogen and are particularly suited for the lubrication of internal surfaces of uncured or unvulcanized envelopes useful for the manufacture of rubber pneumatic or semi-pneumatic tires for vehicles, as well as for vulcanization bladders useful for the shaping and vulcanizing of pneumatic or semi-pneumatic tires. | 04-01-2010 |
20100310780 | PROCESS FOR COMBATING THE APPEARANCE OF HAZE DURING THE COATING OF FLEXIBLE SUPPORTS WITH A CROSSLINKABLE LIQUID SILICONE COMPOSITION, IN A ROLL DEVICE - Coating of flexible materials with liquid compositions is disclosed. The compositions advantageously comprise one or more polyorganosiloxanes crosslinkable by polyaddition, by dehydrocondensation, by polycondensation, cationically or free-radically to form a protective coating or film having, in particular, release and/or water-repellency properties. | 12-09-2010 |
20110015332 | Oil-in-water aminosiloxane emulsions - Oil-in-water siloxane emulsions are useful for providing a substrate, especially a textile substrate, with long-lasting water-repellent properties. | 01-20-2011 |
20110190415 | Aqueous silicone dispersions, formulations, especially paint formulations, containing them and one of their methods of preparation - The invention relates to an aqueous silicone dispersion, containing one or more polyorganosiloxanes (POSs) intended to be crosslinked or having been crosslinked by elimination of water or alcohol, according to a polycondensation mechanism. The present invention also relates to methods for preparing aqueous silicone emulsions and dispersions. | 08-04-2011 |
