ABSTRACT:
Organopolysiloxane compositions suitable for use in a liquid injection molding process of elastomeric articles are produced by mixing a vinyl-endblocked polydiorganosiloxane fluid copolymer containing dimethylsiloxane units and methyl-3,3,3-trifluoropropylsiloxane units, a treated, reinforcing silica filler, a platinum-containing catalyst, a curing agent comprising dimethylhydrogensiloxane units as the only source of silicon-bonded hydrogen atoms and, as an inhibitor for the platinum-containing catalyst, certain olefinic siloxanes and/or acetylenic siloxanes. These compositions are especially suited for liquid injection molding because they can be stored at room temperature for days and can be injected into a hot mold with pressures less than 352 kg./sq.cm. (5,000 psi) whereon they cure rapidly to an elastomeric article having a tensile strength greater than 42 kg./sq.cm., and elongation at break greater than 300 percent and a tear strength greater than 7 kg./cm.
