A process for preparing an aqueous dispersion of a silicone resin is disclosed by reacting a mixture containing an alkylalkoxysilane and a cationic alkoxysilane to form a self dispersing silicone resin and subsequently combining the silicone resin with water to form the dispersion. The resulting dispersions are useful for forming coatings on various substrates that are essentially free of co-surfactants or volatile organic solvents.

To provide a method that efficiently produces a silicone oil composition in which cross-linked silicone particles uniformly dispersed in amino-modified silicone oil. This invention is a method of producing a silicone oil composition, characterized by removing water after mixing an aqueous suspension of cross-linked silicone particles having an average particle diameter in the range of 0.1 to 500 µm with an aqueous emulsion of an amino-modified silicone oil having an average emulsion particle diameter in the range of 0.05 to 100 µm.

The instant invention provides a high-solid, solvent-free alkyd dispersion, and a continuous process for producing the same. The aqueous alkyd dispersion, according to the present invention comprises (a) from 40 to 70 percent by weight of one or more alkyds based on the total weight of the dispersion, wherein each one or more alkyds has an acid value of less than 20 and a molecular weight (Mn) in the range of greater than 1000 Dalton; (b)from less than 10 percent by weight of one or more surfactants, based on the total weight of the dispersion; and (c) from 30 to 55 percent by weight of water, based on the total weight of the dispersion; and the dispersion has an average particle size diameter in the range of 0.05 to 5 µm.
