ABSTRACT:
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.
