Abstract
Abstract What is disclosed are aqueous emulsions which are formed by the use of certain organofunctional cationic silanes. The emulsions are stable and are formed using reactive silanes that allow the transfer of water immiscible liquids and the silanes to certain substrates with the avoidance of any subsequent re-wetting or re-solubilizing of the silane or water immiscible liquid, and subsequent loss from the surface thereof.
