COATING GRADE CMC - INSTANT

Sodium carboxymethyl cellulose (CMC) functions as a thickening agent, stabilizer, and water-retaining agent in coatings, and has a significant effect on optimizing and enhancing the performance of coatings.

Water-based coatings: Thickening and stabilization

Adding CMC to latex paint can increase the viscosity of the coating, prevent the sedimentation of pigments and fillers, and improve the leveling property during the construction process.

Putty: Water Retention and Adhesion

Adding CMC to the interior wall putty powder can enhance its water retention property, extend the curing time, make the putty easier to apply, prevent cracking after drying, and increase the bonding strength.

Tile adhesive: Improves workability

Adding CMC to the tile adhesive improves the anti-falling property and flexibility; during construction, it is easier to adjust the position, and after curing, the bond becomes very strong.

Low-cost coating formula

CMC can replace part of HEC (hydroxyethyl cellulose) or HPMC (hydroxypropyl methylcellulose). While maintaining the basic performance of the coating unaffected, it can significantly reduce the raw material cost, with a reduction rate of up to 20% - 30%.

Special function coating

Adding CMC to the fireproof coating can delay the evaporation of moisture and promote the uniform distribution of the flame retardant; the coating becomes denser and the fire resistance performance is enhanced.

Comparison of alternative solutions

In the comparison between CMC and HPMC, both have their own advantages and disadvantages. CMC has the advantage of lower cost, but it performs relatively poorly in terms of water resistance; while HPMC is suitable for scenarios with higher requirements for weather resistance.
