  • Patent number: 9976105
    Abstract: Silicone oil-in-water emulsions containing a polysiloxane containing polymer is prepared by first preparing a polysiloxane containing polymer by the polymerization of siloxane containing monomers and/or oligomers in the presence of an inert organopoly siloxane and/or an organic fluid, a suitable catalyst and optionally an end-blocking agent; and quenching the reaction if required. If required one or more surfactants may be introduced into the polysiloxane containing polymer to form a homogenous oil phase. Water is then added (in an amount of 0.1-10 percent by weight based on total oil phase weight) to the homogenous oil phase to form a water-in-oil emulsion. Shear is applied to the water-in-oil emulsion to cause inversion of the water-in-oil emulsion to an oil-in-water emulsion. Finally, if required the oil-in-water emulsion can be diluted by adding more water.

  • Patent number: 8232346
    Abstract: The invention relates to an aqueous silicone emulsion comprising polyorganosiloxanes (POS) with Si-vinyl units and POS with SiH units, cross-linkable by polyaddition in the presence of a platinum catalyst. The emulsion also contains an agent (e.g., buffer) for setting and maintaining pH between 5 and 9 in an amount sufficient to eliminate or significantly reduce foam or gel formation; an emulsifying agent; optionally a polyaddition inhibitor and other additives such as a filler, biocide, antifoam, anti-freeze, coloring agent, synthetic latex. The emulsions can comprise three different families of dispersed silicone phase droplets (e.g., polyorganosiloxane (A), polyorganosiloxane (B) and catalyst). Such emulsions can be used in the preparation of anti-adherent coating on fibrous or non fibrous supports. The invention also concerns a method for preparing said emulsions and methods for coating supports, for example paper, using said emulsion.

  • Patent number: 8202931
    Abstract: The present invention relates to a novel polymer, an adhesive composition including the same, and a rubber reinforcing material treated with the same, and more particularly to an organic polysiloxane including a certain repeating unit, an adhesive composition including the same, and a rubber reinforcing material treated with the same. Because the organic polysiloxane and the adhesive composition including the same is superior in reactivity to a hydroxyl group, an amide group, or an amine group, and has high thermal resistance and low stiffness, the composition is preferably used for surface-treating a rubber reinforcing material such as a tire cord and make it possible to provide a rubber reinforcing material such as a tire cord having good properties.
