Abstract: Present application relates to an aqueous based, salt-free, stable fluid suspension composition comprising: (i) about 0.01 wt. % to about 30 wt. % of at least one cellulose ether, (ii) about 0.01 wt. % to about 90 wt. % of at least one insolubilizing agent selected from the group consisting of monosaccharide, disaccharide, polysaccharide, inverted sugar, and combinations thereof, (iii) about 0.01 wt. % to about 5 wt. % of at least one stabilizing agent, (iv) about 0.01 wt. % to about 5 wt. % of at least one preservative, and (v) about 0.01 wt. % to about 70 wt. % of water.

Abstract: Hydroxyethylcellulose with a low molar substitution and which is uniformly substituted is useful in cement-based systems, including mortars. The cement-based system exhibits long pot life, as well as very high water retention capability at hot temperature, as well as better paste stability and optimized setting behavior for hot as well as cold temperature compared to typical, cement-based systems with commercial cellulose ether compounds. Less hydrophilic cellulose ethers such as methylhydroxyethylcellulose can be added as a second cellulose ether.

Abstract: 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.
