摘要： This invention describes a method of producing a silicone elastomer from an emulsion. When the ingredients are mixed together, the resulting latex can be used immediately. Removing the water from the latex results in a silicone elastomer. The method combines (A) an anionically stabilized, hydroxyl endblocked polydiorganosiloxane, present as an emulsion of dispersed particles in water, the emulsion having a pH of greater than 9, (B) dialkyltindicarboxylate, (C) alkylorthosilicate, (D) colloidal silica, and optionally (E) water, admixing (A) and (B) only in the presence of (C) to produce a dispersion of the ingredients in water. The ingredients can be distributed into a two-part system for storage. One embodiment includes fibers, lauryl alcohol, or a mixture of both in the emulsion; then forms an open-cell, elastomeric foam by forming a froth from the emulsion and removing the water from the froth.

摘要： 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.

摘要： 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.

摘要： Moisture curable, foamable compositions that do not slump appreciably in the uncured state when applied on a vertical surface, consist essentially of an RTV elastomeric composition, from 10 to 50 weight percent of a liquified blowing agent and less than 12 weight percent finely divided filler. The RTV elastomeric composition comprises the product obtained by mixing at least two moisture curable polydiorganosiloxanes with an effective amount of a moisture reactive crosslinker. A graft copolymer derived from a liquid polydiorganosiloxane and an ethylenically unsaturated organic monomer constitutes from 5 to 80 weight percent of the polydiorganosiloxanes.
