Abstract: A thermally conductive silicone composition is shown and described herein. The thermally conductive silicone composition comprises (A) an ionically modified siloxane, and (B) a thermally conductive filler comprising a first filler and a second filler, where the first filler and/or the second filler comprises a plurality of filler types, the plurality of filler types differing from one another in terms of particle size and/or morphology. The ionically modified siloxane may function as a dispersing aid or wetter for efficient dispersion of thermal conducting organic and inorganic fillers to achieve high thermal conductivity.

Abstract: A silicone resin emulsion composition, coating compositions comprising such emulsions, and methods of making such emulsions is shown and described herein. The composition comprises a silicone resin, a surfactant, and an emulsion promoting agent. The emulsion promoting agent comprises a hydrophobically modified polyether. The use of the hydrophobically modified polyether along with the surfactant provides a silicone emulsion that is stable.
