Abstract
A mixture of a hydroxyl endblocked polydimethylsiloxane, ethylpolysilicate, a silane of the formula EQU RSi(O--N.dbd.CR'R.sup.2).sub.3 where R is methyl or vinyl and each R' and R.sup.2 is methyl or ethyl, organotin carboxylate, an extending filler and organic solvent provides dispersions which cure to silicone elastomers at room temperature. These compositions have long storage life sufficient to permit storage in a single container for extended periods of time. These compositions can be prepared extrudable or sprayable, are pigmentable, have high strength, and are readily prepared.
