摘要： Room temperature-storable, heat-curable organopolysiloxane compositions which comprise silicon-bonded vinyl radicals, silicon-bonded hydrogen atoms, a platinum-type compound and an unsaturated hydrocarbon compound of the conjugated ene-yen type provide a realease surface for tacky substances when coated onto the surface of a base material and heated, even mildly. The release surface possesses a time-stable release ability, particularly for pressure sensitive adhesive bearing articles such as tapes and labels.

摘要： Organopolysiloxane compositions which react by way of a hydrosilylation reaction to undergo an increase in viscosity have improved resistance to reaction at room temperature (longer pot life) and/or an improved reaction rate at elevated temperature (shorter cure time) than analogous compositions of the art by incorporating therein an unsaturated hydrocarbon having from 6 to 10 carbon atoms, a terminal acetylenic linkage and an olefinic linkage conjugated therewith. The resulting compositions are useful for preparing various cured siloxanes such as resins, elastomers, gels and foams.
