Abstract
A process for preparing emulsions of silicone gums is disclosed based on using an ethylene oxide/propylene oxide block copolymer as the emulsifier. The emulsions produced by the present process are useful as coatings additives for both water-based and oil-based coatings to obtain improved slip and anti-mar properties. The emulsions may also be used in the manufacture of tires as band ply lubricants. They may also be used in personal care applications.
