ABSTRACT:
This invention discloses a method of controlling the relative physical properties of foams such as density and compressibility or density and Bashore resiliency for compositions which consist essentially of triorganosiloxy endblocked polydiorganosiloxane having at least two vinyl radicals, platinum catalyst, organohydrogensiloxane, and hydroxyl endblocked polydiorganoisiloxane. The relative values of the physical properties are adjusted by the addition of varying amounts of organic alcohol having from 3 to 12 carbon atoms to the composition.
