摘要： A foam mixer-applicator for mixing a two-part foamable composition includes a mixing head having a mixing chamber for impingement mixing of the two component parts of the foamable composition, which are supplied to the mixing chamber in a pre-pressurized state. The mixing head is sealingly connected to a dispensing head having a foaming chamber of a substantially greater capacity than the mixing chamber and an outlet port for discharging the foam composition after foaming and acquiring a higher, yet flowable viscosity. A pneumatic plunger system pushes the foamed composition through an outlet port of the dispensing housing onto a substrate.

摘要： This invention relates to a method of producing silicone elastomeric foam of low density. The method mixes polydiorganosiloxanes having hydroxyl endblocking or vinyl endblocking or mixtures of both along with water to react with silicon hydride in the presence of platinum catalyst to release hydrogen gas to create a froth which cures to a foam. The combination of ingredients allows the manufacture of silicone foam having different combinations of properties than those obtained from previous methods. Embodiments of the invention also make use of specific profoamers and specific alcohols to further modify the properties of the foams produced. The method of this invention yields a low cost, low density, silicone elastomeric foam having physical properties which enable it to be used in cushioning and sealing applications.

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, a liquified blowing agent and finely divided silica. The RTV elastomeric composition comprises the product obtained by mixing (1) at least two hydroxyl endblocked polymers selected from diorganosiloxane homopolymers and copolymers, and (2) an effective amount of a moisture reactive crosslinker for the hydroxyl endblocked polymer where from 0 to 80% by weight of said hydroxyl enblocked polymers is a graft copolymer derived from a liquid polydiorganosiloxane and an ethylenically unsaturated organic monomer. When the silica content is less than 10 percent by weight of the composition or the blowing agent concentration exceeds 20 percent by weight of said composition, the composition contains a slump inhibiting amount of said graft copolymer.

摘要： A method of producing elastomeric silicone foams from a two-part system is disclosed. The method mixes the ingredients then allows a froth to form and cure at ambient temperature to an elastomeric silicone foam. The method mixes a vinyl-containing polydiorganosiloxane (1), a hydroxylated polydiorganosiloxane (2), a platinum catalyst (3), an organohydrogensiloxane (4) and a profoamer (5). The profoamer is a resinous, benzene-soluble organosiloxane copolymer consisting essentially of SiO.sub.4/2 units, silicone bonded hydroxyl groups, (CH.sub.3).sub.3 SiO.sub.1/2 units, and fluorine-containing units. An embodiment of the method includes a liquified blowing agent and stores the mixture under superatmospheric pressure, forming a foam by releasing the mixture to atmospheric pressure. Another embodiment includes an alcohol in the mixture to provide a foam of lower density. When lauryl alcohol is used and the alcohol is mixed with (1), (3), and (5) before (2) is admixed, the foam has a Bashore resiliency of less than 20.

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.
