ABSTRACT:
The presence of immiscible silica treating agents in high viscosity, pumpable polyorganosiloxane compositions alters the rheology of these compositions sufficiently to permit fabrication of unsupported profiles that retain their initial configuration during heat curing. The immiscible treating agent constitutes from 20 to 100 percent by weight of the total treating agent present in the composition.
