Publication number: 20120315489Abstract: The present invention relates to mortars which include a blend of cellulose ether compounds and exhibit improved pot life, water retention capability, and open time, as well as high tensile strength values. These mortars can be used in the fabrication of external insulation finishing systems (EIFS), particularly in hot environments. The cellulose ether blend includes hydroxyethylcellulose ether and methylhydroxyethylcellulose ether. Water soluble anionic polyacrylamide and hydroxypropyl starch can also be added to the mortar.Type: ApplicationFiled: May 31, 2012Publication date: December 13, 2012Inventors: Wilfried Adolf Hohn, Brigitte Rennert, Martin Wunderlich, Michael Dittel, Teng-Shau Young

Patent number: 8329800Abstract: An aqueous binder composition comprising: a) a water-insoluble polymer (P) in the form of dispersed polymer particles having a glass transition temperature in the range from ?50° C. to 50° C., obtained by free-radical polymerization of ethylenically unsaturated monomers M, the monomers M comprising: 80% to 99.9% by weight, based on the total amount of monomers M, of at least one neutral, monoethylenically unsaturated monomer M1 of low water-solubility; and 0.1% to 20% by weight, based on the total amount of monomers M, of at least one monoethylenically unsaturated monomer M2 which carries at least one carboxyl group and/or at least one carboxamido group (CONH2); and b) boric acid and/or at least one salt of boric acid is provided. Also provided are a process to prepare the binder composition and the use thereof.Type: GrantFiled: December 21, 2009Date of Patent: December 11, 2012Assignee: BASF SEInventors: Alexandre Terrenoire, Frank Reinhold, Stephan Amthor, Michael Gross, Konrad Roschmann, Stefan Becker, Kamesh Vyakaranam, Jens Hartig

Patent number: 8323400Abstract: An additive composition for mortars, exterior insulation finish systems, self-leveling compounds and joint compounds is disclosed. The additive composition contains a nitrogen-containing polymer and a reactive agent capable of forming a crosslinking reaction with the nitrogen-containing polymer. Small amounts of the additive composition contained in a product not only can increase one or more properties of the product but can also minimize the use of redispersible polymers in the product.Type: GrantFiled: November 26, 2008Date of Patent: December 4, 2012Assignee: Celanese International CorporationInventors: Eduardo Romero-Nochebuena, Jose A. Briones, Mark G. Cupta, Philip J. Brondsema
