Abstract
A composition useful in producing an open-cell, elastomeric silicone foam combines a silicone oil-in-water emulsion, which forms an elastomer upon removal of the water, with an aerosol propellant. When the composition is discharged to atmospheric pressure, a froth is formed. Removing water from the froth yields an open-cell foam. The froth is stabilized by surfactants, thickeners, or froth stabilizers selected from fibers or lauryl alcohol.
