Abstract
A stable and highly productive method for the preparation of silicone foam having uniform cells characterized by mixing the base and curing agent portions of an organosiloxane, along with a gas-containing hollow filler in a mixing device having a shear-stirring mechanism such that the organosiloxane begins to foam and cure when the shear-stirring mechanism is used to rupture the filler and mix the base and curing agent portions.
