Dow patents silicone resin emulsion process.
* Patent No. US 6,737,444 B1: Dew Coming Corp., Midland, MI,
patented a method to make an aqueous silicone resin containing emulsion
by mixing a silicone resin blend, a non-resinous silicone polymer and an
inversion assisting polymer to form a homogeneous oil phase; mixing one
or more surfactants with the homogenous oil phase; adding water to the
mixture to cause an inversion of the continuous phase and the dispersed
phase, forming an oil-in-water emulsion; diluting the oil-in-water
emulsion by adding more water and recovering an oil-in-water emulsion
with silicone particles ranging 0.1-5 microns in size.
