sodium carboxymethyl cellulose
Nota de aplicación
A water-soluble polymer, commonly known as carboxymethylcellulose (CMC), composed of the sodium salt of modified cellulose. A viscous gel when dispersed in water at low concentrations, CMC forms a tough, non-soluble film in reaction with heavy metal salts. In conservation, it is used as an adhesive and as a poultice for cleaning stone.
