US Patent:

41429117, Mar 6, 1979

Filed:

Dec 5, 1977

Appl. No.:

5/857803

Inventors:

Jeffrey R. Ellis - Hightstown NJ
Herman B. Wagner - Perkasie PA

Assignee:

Tile Council of America, Inc. - Princeton NJ

International Classification:

C04B 702

US Classification:

106 97

Abstract:

There is provided a new sag resistance imparting agent selected from among gelatinous metal hydroxides and metal salts capable of forming a gelatinous or hydrated hydroxide in the presence of a water soluble alkaline material, the agent being useful for providing sag resistance in various adhesive compositions including (a) hydraulic non-dry-set compositions comprising an hydraulic cement or plaster of paris, and (b) non-hydraulic compositions comprising a room temperature hardening polymer in the form of a resinous liquid or an emulsion, suspension, dispersion, partial solution or total solution. Methods of imparting sag resistance to adhesive compositions such as the aforementioned and methods of use for the sag resistant compositions in the installation of wall and floor covering surfaces are also provided.

Filed:

Oct 7, 1985

Appl. No.:

6/785206

Inventors:

Jeffrey R. Ellis - East Windsor NJ
Martin B. Dines - late of Laguna Beach CA

Assignee:

Occidental Research Corporation - Los Angeles CA

International Classification:

G21F 110

US Classification:

523137

Abstract:

A composition of matter including a polymer sensitized to the heating effects of microwave energy which comprises said polymer and a microwave sensitizing amount of a particulate, layered compound comprising a tetravalent atom and a pentavalent atom, selected from the group consisting of elements of Group V of the Periodic Table of the Elements, and having an atomic weight of greater than 30, dispersed throughout said polymer.

Filed:

Oct 4, 1979

Appl. No.:

6/081811

Inventors:

Jeffrey R. Ellis - Hightstown NJ
Herman B. Wagner - Perkasie PA

Assignee:

Tile Council of America Inc. - Princeton NJ

International Classification:

C04B 735

US Classification:

106 90

Abstract:

There are provided dry-set cement mortars comprising hydraulic cement and water soluble, high molecular weight polymers and gelatinous metal hydroxides and metal salts capable of forming gelatinous or hydrated hydroxides in the presence of aqueous base. These metal hydroxides and metal salts may be the hydroxides or salts of aluminum, the transition element metals, and the mixed salts of alkali metals or ammonium with certain trivalent metallic cations together with the appropriate anions. The novel sag resistant compositions allow for the replacement of asbestos fibers which are used to impart sag resistance in state-of-the-art dry-set Portland cement mortars.
