1. Superior water resistance and long-lasting film durability;
2. High film fullness with uniform distribution, achieving high-gloss effects;
3. Acts as a stabilizer to prevent film separation caused by sudden temperature changes;
4. Functions as a protective colloid, maintaining system stability across a broad pH range;
5. Serves as a thickener to ensure uniform coating distribution, optimize storage and application viscosity, and prevent phase separation;
6. Enhances leveling properties, anti-splash, and anti-sagging performance, improving construction workability;
7. Promotes homogeneous dispersion of pigments and fillers, delivering excellent pigment adhesion.

Application in Latex Paints
Latex paint primarily consists of polymer aqueous dispersions and pigment aqueous dispersions. Its viscosity directly impacts sedimentation, brushability, roll-coating performance, film fullness, and sagging on vertical surfaces. CMC, with its superior rheological properties, low brush resistance, and ease of application, is employed as a stabilizer, thickener, and water-retention agent.
1. Efficient thickening of latex paint with notable viscosity enhancement;
2. Strong stability, maintaining consistent viscosity and residue-free storage;
3. Controls moisture release on porous substrates and retains water under high latex content;
4. Broad compatibility with formulations, minimally affected by emulsion types, dispersants, or surfactants;
5. Terminates aqueous interactions post-application, restoring viscosity to prevent sagging.
Application in Casting Paints
CMC, a multi-chain macromolecular compound, swells in water to form an interlinked network structure through linear chain expansion. It synergizes with sodium bentonite to enhance suspension capacity, reduce sediment agglomeration, and prevent fire-resistant aggregates from settling. It is widely used to improve the suspension rate and viscosity control of casting paints.
1. Superior water-soluble thickening properties, optimizing coating viscosity and rheology;
2. Excellent solubility and dispersion, ensuring solid particles remain suspended in the carrier liquid;
3. Forces fire-resistant powders to suspend, preventing sedimentation and excessive liquid penetration;
4. Enhances coating spreadability and coverage, improving brushing and leveling performance;
5. Post-drying, particles bond firmly, adhering tightly to the mold’s inner and outer surfaces.
