The present invention relates to hybrid aqueous silicone-organic composition which are prepared by first forming a silicone oil-in-water emulsion by dispersing an oil phase, containing a silicone polymer and a specific non-ionic surfactant, in a water phase containing a poly(vinyl alcohol) dissolved in water. This silicone emulsion is subsequently mixed with a an aqueous solution of a water-soluble polymer to form the instant compositions which can be applied to substrates to provide coatings having heat resistance comparable to conventional all-silicone systems delivered from organic solvent solution.

Aqueous siliocone-organic hybrids

A curable, reinforced polydiorganosiloxane microemulsion is prepared by adding from 5 to 30 parts by weight of colloidal silica per 100 parts by weight of polydiorganosiloxane in the microemulsion and from 1 to 5 parts by weight of dialkyltindicarboxylate catalyst per 100 parts by weight of the microemulsion to polydiorganosiloxane microemulsion. The curable, reinforced polydiorganosiloxane emulsion can be cast into coherent, elastomeric films of less than 0.4 micrometer thickness.

Film forming silicone microemulsions

A polydiorganosiloxane emulsion having a combination of high polymer content and low viscosity can be produced by blending a high polymer content polydiorganosiloxane macroemulsion, having a polymer content of greater than 60 percent by weight and an average particle size of greater than 0.14 micrometers, and a high polymer content polydiorganosiloxane microemulsion, having a polymer content of from 20 to 30 percent by weight and an average particle size of less than 0.14 micrometers, with the ratio of the average particle size of the macroemulsion to the average size of the microemulsion of from 5 to 15.
