　　3.Description

　　Sodium Carboxymethyl Cellulose is a cellulose derivative with carboxymethyl groups bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose.

　　4.Properties

　　“YUYU” CMC is a kind of ionic water soluble cellulose ether and has the following excellent performance in the coating：

　　（1） Water soluble：able to be dissolved in hot water or cold water with simple stirring equipment;

　　（2） Extremely low ash content, quite stable and good in dispersion as emulsion thickener, able to improve coating leveling property and sparkling and sagging resistance, thus improving construction performance of the coating;

　　（3） Good compatibility, able to be compatible with water soluble gum, softener and resin;

　　（4） No pharmacological function, nontoxic, harmless to physical body;

　　（5） Well-distributed replacing base, strong anti-bacterium effect.
