Carboxymethyl cellulose CMC-Coating grade
Coating grade CMC model: IM6D IVH9D
CMC can be used in water-based interior and exterior wall coatings instead of HEC, and has good cost performance. Through the chemical modification of the product surface, it has good dispersion performance in aqueous solution, no agglomeration, fast dissolution speed and convenient use. It is an economic multi-purpose additive that can be used in coatings. It has the functions of thickening, controlling leveling, water retention and maintaining dispersion stability. Compared with other cellulose ether products, it shows better splash resistance.
CMC-Application In Coating Industry
- After chemical treatment, it has good dispersion;
- It can dissolve quickly after adding alkali;
- The solution has no fiber and good transparency;
- Very few gel particles, filter screen will not be blocked, easy to use.
- Various viscosity ranges and good viscosity stability;
- The reaction is uniform and has good resistance to enzyme denaturation;
- Good heat resistance.
