    摘要: An emulsion is made by dispersing a siloxane in water by forming a mixture of water, a cyclic siloxane, and an ethoxylated alcohol nonionic surfactant. An organosilanolate initiator is used, and the mixture is free of other surfactants which bear a charge. The cyclic siloxane is polymerized until an emulsion is formed, and the emulsion is free of electrical charge. The emulsion is more compatible in the personal care arena.

    摘要: Fluorescent organopolysiloxane compounds which bear two or more reactive silicon-bonded sites are useful as durable markers in curable silicone compositions. Having more than one reactive site the compounds participate in the curing reaction of the curable composition and thus do not adversley affect its curing behavior. The resulting fluorescent curable compositions are particularly useful in the preparation of adhesive-release coatings.

    摘要: A radiation curable protective coating composition is disclosed which contains at least one multifunctional acrylate or methacrylate monomer and colloidal silica dispersed in water or an organic solvent/water mixture. When applied to a substrate and radiation cured, the composition forms a transparent abrasion resistant, weather resistant, ultraviolet light resistant, coating firmly held thereon.

    摘要: The present invention provides methods for separating one or more components of interest from a sample containing particulates and soluble materials. The method comprises the steps of: (a) filtering a sample through silica filter media whose surface silanol groups have reacted with one or more silanes, and (b) simultaneously capturing particulates and binding a soluble component to the silica filter media. The bound soluble component of interest is subsequently eluted from the silica filter media. In one embodiment of the invention, unwanted soluble materials are captured by the treated silica filter media and desired component of interest is recovered from the flow-through. In another embodiment, different components of interest are recovered from both the eluate and the flow-through. Preferred treated silica filter media are silane-treated rice hull ash or diatomaceous earth with functional quarternary ammonium group or functional sulphonate group. The present invention also provides silane-treated silica filter media.
