    摘要: The present invention relates to a dispersible silicone composition comprising (I) a silicone composition prepared by reacting (i) a polyorganosiloxane, (ii) a silicon compound, optionally (iii) a finely divided filler, and (iv) a catalytic amount of a compound for promoting the reaction of the other components and (II) mineral oil. The mineral oil is effective as a dispersing agent for the silicone composition (I). The mineral oil-containing compositions are easier to handle, and produce less waste and its dispersion into mineral oil based formulations is more efficient.

    摘要: A silicone composition having a continuous phase of a polar organic liquid including particles of a silicone active material encapsulated within an organic encapsulating material which is a solid at 25° C. The silicone active material is sparingly soluble in the polar organic liquid at 25° C., but is substantially dissolved in the polar organic liquid at temperatures of from 40 to 100° C. The three phase contact angle between the organic encapsulating material, the silicone antifoam, and the polar organic liquid is below 130° C., with the angle measured through the silicone.

    摘要: The present invention relates to a method for controlling foam in a foam producing system comprising adding to the foam producing system a dispersible silicone composition comprising (I) a silicone composition prepared by reacting (i) a polyorganosiloxane, (ii) a silicon compound, optionally (iii) a finely divided filler, and (iv) a catalytic amount of a compound for promoting the reaction of the other components and (II) a hydrocarbon oil. The hydrocarbon oil is effective as a dispersing agent for the silicone composition (I). The hydrocarbon oil-containing compositions are easier to handle, and produce less waste and its dispersion into mineral oil based formulations is more efficient.

    摘要: A mixture of carbonyl iron powder and a silicone resin containing silica siloxane units and silanol groups can be stabilized for storage by mixing a stabilizing amount of an halosilane with the mixture; monochlorosilanes are preferred. The small amount of halosilane that is needed can be further reduced by vacuuming the mixture before adding the halosilane. The stabilized compositions are useful as reactive components in curable silicone mixtures.
