CMC for Paints and Ceramics
CMC can be used in ceramic body, glazing pulp, and decoration. Used in ceramic body, it is a good strengthening agent, which can strengthen the mouldability of mud and sand materials, help the shaping of the base and increase the folding strength of the green body. Used in glazing pulp and decoration, it is a binder that plays a role of suspending, uncoagulating, and keeping water.
