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.
