Abstract: A process is disclosed for making a silicone-in-water emulsion by forming a hydrophobic phase containing a silicone component, mixing one or more surfactants with the hydrophobic phase, adding water to the hydrophobic phase and shear mixing in a twin-screw extruder to form a silicone in water emulsion.

Abstract: High viscosity silicone compositions such as silicone gums, silicone rubbers, silicone elastomers, and silicone resins, are emulsified by mechanical inversion in which silicone water-in-oil (W/O) emulsions are inverted to silicone oil-in-water (O/W) emulsions. Silicone resins with a viscosity of about one billion centistoke (mm2/s), i.e., 1,000,000,000 centistoke (mm2/s) have been emulsified. These silicone O/W emulsions are useful in personal care products where they are capable of providing improved aesthetics. They are also useful in products used in the paper industry and medical industry. The silicone O/W emulsions are easier to handle than the high viscosity silicone in the emulsion, which enables the emulsions to mixed with other emulsions or other water-soluble ingredients.

Abstract: Water-continuous emulsion of curable elastomeric polymers are disclosed having a solids content of greater than 75%, an average particle size less than 5 ?m, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water comprising; a curable elastomeric polymer, surfactant, internal cure additive, water, optional plasticizer, and optional low molecular weight acid. The water-continuous emulsions of curable elastomeric polymers can be prepared by; (I) forming a premix comprising an elastomeric polymer, surfactant, and internal cure additive, and (II) adding water to the premix with mixing to form a water continuous emulsion of the curable elastomeric polymer having a solids content of greater than 75%, an average particle size less than 5 ?m, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water.

The water-continuous emulsions of silylated elastomeric polymers can be prepared by; (I) forming a premix comprising an elastomeric polymer and surfactant, and optionally a plasticizer and low molecular weight acid, and (II) adding water to the premix with mixing to form a water continuous emulsion of the silylated elastomeric polymer having a solids content of greater than 75%, an average particle size less than 5 &mgr;m, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water.

Abstract: A curable coating composition comprises: (A) a water continuous emulsion comprising a curable elastomeric polymer having a viscosity of 0.5-1,000,000 KPa-s and a glass transition temperature up to 50° C.; (B) an aqueous polyurethane dispersion; and optionally, (C) a cure agent. Methods for preparing the curable coating compositions are also disclosed. The curable coating composition and the cured coatings derived from the reaction product of this composition are useful as fabric coatings, and in particular for decreasing air permeability of the coated fabrics at relatively lower coating weights.
