Carboxymethylcellulose Ceramic Binder
CAS Number: 9004-32-4
Sodium carboxymethylcellulose (CMC) is an anionic cellulose derivative used as a binder, thickener, and dispersant in ceramic slips, glazes, and pressing powders. It improves green strength and workability while acting as a co-deflocculant in aqueous ceramic suspensions. CMC burns out cleanly, making it suitable for technical and traditional ceramics.
