Patent number: 4737525Abstract: Thixotropic silicates and stable emulsions are produced by reacting a salt-forming compound such as mineral acids and a powdered natural silicate in a liquid organic compound. The thixotropic silicate such as minerals containing silicates may be utilized to produce stable organic compound-silicate emulsion, as an anti-sag material, as a filler and as a thickener. It may be further chemically reacted along with the organic compound to produce useful foams, resins, coating agents and fillers.Type: GrantFiled: January 5, 1987Date of Patent: April 12, 1988Inventor: David H. Blount

Patent number: 4731389Abstract: The invention relates to foams for insulating cavities and structures, such as spaces between walls in houses. The inventive foam compositions are prepared in separate portions, generally comprising (A) cement and (B) foam. Air is added initially to foam one of the components or a mixture of components.In a first embodiment, the first component comprises an aqueous solution of polyvinyl alcohol and a dispersant. This component is mechanically foamed by injection of air, for example. After the mechanical foaming a second, cement component is added to the first component. This second component comprises an aqueous solution, mixture or suspension of magnesium oxide and barium metaborate, and a dispersant.In a second, preferred embodiment, the first component comprises an aqueous solution of polyvinyl alcohol and calcium chloride, which component is mechanically foamed by injection of air.Type: GrantFiled: November 14, 1985Date of Patent: March 15, 1988Assignee: Air Krete, Inc.Inventors: R. Keene Christopher, Donald Thomson

Patent number: 4719243Abstract: The specification is directed to polysiloxane foams. There are disclosed compositions capable of curing at room temperature which comprise a hydroxypolysiloxane, an alkylhydrogen polysiloxane, a tin compound as catalyst and finely divided filler. According to the invention storage stability of these foam forming polysiloxane compositions is improved by use as filler of silica which has been pretreated to render is hydrophobic. The subject compositions may comprise two components which do not require individual mixing prior to mixing together of the components. The compositions may be packaged in any convenient manner. The compositions may be used for a variety of purposes, for example to provide medical dressings.Type: GrantFiled: November 10, 1986Date of Patent: January 12, 1988Assignee: Dow Corning France S.A.Inventor: David Pocknell
