ABSTRACT:
The presence of a vinyl-specific peroxide in liquid organosiloxane compositions curable to elastomers by a platinum-catalyzed hydrosiliation reaction imparts excellent recovery properties to the elastomers without requiring post-curing. To avoid premature curing the compositions are preferably stored and transported in at least two parts, where the organohydrogensiloxane curing agent and the hydrosilation catalyst are located in different parts of the composition.
