CMC, or sodium carboxymethyl cellulose, is a significant type of cellulose and a highly water-soluble polyanionic compound derived from chemically modified natural fibers. It is soluble in cold water. CMC possesses exceptional and highly valuable comprehensive physical and chemical properties, such as emulsifying ability, dispersion, solid dispersion, non-perishability, and physiological harmlessness, making it a widely used natural polymer derivative.

The superior characteristics of sodium CMC include thickening, water retention, metabolic inertness, film-forming ability, dispersion stability, and more. Due to these properties, it can be utilized as thickeners, water retention agents, binders, lubricants, emulsifiers, auxiliary deflocculants, tablet bases, biological substrates, and carriers for biological products.

Coating Grade CMC

CMC is employed in coatings and exhibits excellent thickening, dispersibility, and stability. It enhances the stability of the emulsion polymerization system, ensuring that the coating achieves superior pigment adhesion. Furthermore, it boosts the viscosity and leveling of the coating emulsion, thereby improving the application performance of the coating. Notably, CMC allows for long-term storage without precipitation, is environmentally friendly and safe, and poses no toxicity or harm. Consequently, it finds widespread application in various coatings, including latex paints, water-based interior and exterior wall paints, and casting coatings.

CMC is utilized in coatings due to its impressive thickening capability, dispersibility, and stability. It plays a crucial role in enhancing the stability of the emulsion polymerization system, resulting in coatings with superior pigment adhesion. Furthermore, it boosts the viscosity and leveling properties of the coating emulsion, thus improving the overall application performance of the coating. Importantly, CMC can be stored for extended periods without precipitation, making it an environmentally friendly and safe option that is non-toxic and harmless. Consequently, it is widely adopted in various types of coatings, including latex paints, water-based interior and exterior wall paints, and casting coatings.

CMC finds applications in ceramics, specifically in ceramic bodies, glazing slurries, and decorations. When used in ceramic bodies, it serves as an effective strengthening agent, enhancing the plasticity of clay and sand materials, facilitating base shaping, and increasing the bending strength of the greenware. In glazing slurries and decorations, CMC functions as a binder, providing suspension, anti-coagulation, and water retention properties.

Regarding usage:

• In ceramic bodies, the recommended addition rate is 0.03% to 0.2%.
• For glazing slurries, the addition rate ranges from 0.05% to 0.2%.
• In colored glazes, the addition rate is between 1.4% and 4.0%.
