Abstract
A mixture of a hydroxyl endblocked polydimethylsiloxane, ethylpolysilicate, monoorganotriacetoxysilane, organotin carboxylate, an extending filler and organic solvent provides dispersions which cure to silicone elastomers at room temperature. These compositions have long storage life and can be made into compositions which are storable for extended periods of time in a single container if kept under substantially anhydrous conditions. These compositions can be prepared extrudable or sprayable, are pigmentable, have high strengths, and are readily prepared.
