Carboxymethyl Cellulose (CMC) is Cellulose derivative with Carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. CMC are polymers obtained by the chemical reaction of cellulose, caustic soda and chloroacetic acid. CMC are used as binders and thickening agents. In fact, they give more plasticity to the glaze, improve its spreading and avoid glaze shrinkage during firing. The use of these binders improves also the adherence of the glaze to the support and its resistance to chipping during subsequent phases of the production process. The various types of CMC are different in purity and in viscosity levels.

CMC increases the viscosity of the glazes and leads to an excellent leveling. The product has proved very suitable for all application processes (dipping, spraying or double disk application). Depending on the individual requirements, the application quantity should range between 0.1 and 0.5 %.

It improves the adhesive qualities of the glaze when it is applied,delays drying times,makes the glaze spread better on the surface and reduces dust.

In glaze suspensions resicol has the effect of slightly increasing viscosity and suspension.

It is suitable for all types of applications,but it is particularly indicated for single fired tiles.
