Patent number: 8748528Abstract: Disclosed is a coating composition that includes an aqueous emulsion of a hydrophobic acrylic polymer, a water-soluble polymer, and an inorganic filler, and further includes a freezing-point lowering component to permit low temperature application. The freezing-point lowering component will preferably include a water-soluble, corrosion inhibiting salt. The coating composition will also optionally and preferably include an evaporation enhancing component to promote faster drying and skin formation at low temperatures. The coating composition may be coated onto a construction surface (e.g., by spraying) where, after drying, it will form a fully adhered barrier membrane that is water-vapor permeable, but air and liquid-water impermeable. Such membrane will preferably have sufficient coating thickness and sufficiently high elongation that it will bridge joints and cracks.Type: GrantFiled: November 18, 2010Date of Patent: June 10, 2014Assignee: W. R. Grace & Co.-Conn.Inventors: Xia Cao, Robert A. Wiercinski, Neal S. Berke, Antonio J. Aldykiewicz, Jr., Jyoti Seth

Publication number: 20120322902Abstract: Lightweight cementitious foams of the invention have excellent dynamic and dimensional stability due to use of foaming system comprising polycarboxylate surfactant foam generating agent, foam stabilizer (e.g., PVOH), and shrinkage reducing admixture to inhibit plastic shrinkage and micro-cracking of cement. The foaming system can be used in conventional cement mortars or concretes as well as with exemplary cementitious slurry systems of the invention, which include an expansive agent, a cross-linking agent for the foam stabilizer. Microfibers can be used in the foam, slurry, or both, to prevent micro-cracking. Cementitious foams can be made without use of autoclave or lightweight aggregates to achieve enhanced compressive strength and thermal insulation properties that compare favorably with conventional foams and insulation materials at comparable densities.Type: ApplicationFiled: August 24, 2012Publication date: December 20, 2012Inventors: Neal S. Berke, Jordan S. Merritt, Lianfang Li, Antonio J. Aldykiewicz, JR., Robert A. Wierinski, Michael D. Morgan

Patent number: 6045686Abstract: A process for the delacquering and detinning of a metal substrate is presented comprising the fully electrochemical removal of both an outer polymeric coating and an inner tin coating from a metal substrate. The disclosed method provides a clean metal substrate, and results in wastes which are easily disposed of with minimal cost and minimal environmental impact. In one embodiment, the present invention comprises a one-stage process for removing an outer polymeric coating and an inner tin coating from a metal substrate in a single electrolyte bath through electrolytic removal of both the polymeric and tin layers from the metal substrate. An electrically conductive container having the electrolyte bath therein acts as an anode in the process, and the removed tin is plated out on the cathode. In another embodiment, the present invention comprises a two-stage process for removing an outer polymeric coating and an inner tin coating from a metal substrate.Type: GrantFiled: December 15, 1997Date of Patent: April 4, 2000Assignee: The University of ConnecticutInventors: James M.
