20120208952 | Method for Deaerating Liquids - The invention describes a novel method for deaerating liquids by adding 0.0001 to 5.0% by weight, preferably 0.0002-1.0% by weight, especially preferred 0.001-0.2% by weight of branched polyether-polysiloxane copolymers to said liquids. Only those branched polyether-polysiloxane copolymers are used in which the polyether radicals are SiC-bonded via hydrocarbon radicals to linear siloxane chains and said siloxane chains are connected to each other via SiC-bonded organic radicals, preferably divalent to decavalent, preferably divalent to tetravalent, hydrocarbon radicals, which may contain one or more heteroatoms selected from the group consisting of oxygen and nitrogen atoms. | 08-16-2012 |
20120312165 | METHOD FOR DEAERATING LIQUIDS - Efficient deaeration of aqueous suspensions such as those obtained during textile treatment or pulp and paper production is achieved by use of a combination of a polyoxypropylene polyether polymer or copolymer and branched polyether-polysiloxane copolymers. | 12-13-2012 |
20130040871 | ANTIFOAM COMPOSITIONS - Superior defoamer compositions contain a low viscosity linear organopolysiloxane, a higher viscosity, optionally branched organopolysiloxane, a polyethersiloxane with a low cloud point, and both colloidal silica and fumed silica. | 02-14-2013 |
20140316015 | METHOD FOR PRODUCING ANTIFOAM COMPOSITIONS - Effective and long lasting defoamer compositions are prepared by admixing an organopolysiloxanes, a hydrophilic silica, a hydrophobic silica, optionally an organopolysiloxanes resin, and optionally a water insoluble inorganic compound, at a temperature of 50° C. to 250° C. until the viscosity of the composition has decreased to at least half its original viscosity prior to heating. | 10-23-2014 |
20150119509 | DEFOAMER FORMULATIONS COMPRISING ORGANOPOLYSILOXANES - A mixture of unique organopolysiloxane, filler, and additional components are effective defoamers and may be used neat, or in the form of a powder or emulsion. | 04-30-2015 |
