Abstract: A mixture composition of a cellulose ether made from raw cotton linters and at least one additive is used in a ready mixed joint compound composition wherein the amount of the cellulose ether in the joint compound composition is significantly reduced. When this joint compound composition is mixed with water and applied to a substrate, the water retention, sag resistance, and workability of the wet joint compound are comparable or improved as compared to when using conventional similar cellulose ethers.

Abstract: CMC with CMDS greater than or equal to 0.76, optionally with a non-ionic co-thickener or a CMC with CMDS less than 0.75 is used as both the rheology modifier and partial clay substitute in tape joint compounds. This significant reduction of clay level is sufficient to eliminate most of the negative characteristics of clay in joint compound.

Abstract translation: 使用CMDS大于或等于0.76的CMC，任选与非离子共增稠剂或CMDS小于0.75的CMC用作胶带接头化合物中的流变改性剂和部分粘土替代物。 粘土水平的显着降低足以消除接头化合物中粘土的大部分负面特征。

Abstract: The presently disclosed and claimed inventive concept(s) relates generally to a carboxymethylcellulose (CMC) system for use in ready-mix joint compounds. More specifically, the presently disclosed and claimed inventive concept(s) relates to a non-uniformly substituted {"blocky") CMC system for use as an efficient thickener and rheology modifier for ready-mix joint compounds and the use of a reduced amount of clay for improving the joint compounds.

Abstract: A joint compound with improved crack resistance is formed by combining water, a filler such as calcium carbonate, a latex emulsion binder, a thickening system such as methyl hydroxyethyl cellulose, and nanocrystalline cellulose. The nanocrystalline cellulose is provided in an amount effective to reduce the crack formation during drying.
