Carboxymethyl cellulose CMC-Coating grade

Short Description:

Carboxymethylation reaction is one of etherification technologies. After Carboxymethylation of cellulose, carboxymethyl cellulose (CMC) is obtained. Its aqueous solution has the functions of thickening, film-forming, bonding, water retention, colloidal protection, emulsification and suspension. It is widely used in petroleum, food, medicine, textile and papermaking industries. It is one of the most important cellulose ethers.With our long-term expertise in chemical products trading, do we provide you with professional advice on products and tailored solutions for your specific purpose. We are happy to help you choose the materials suitable for you.Just click to find the applications in your industry: CMC in food, petroleum, printing and dyeing, ceramics, toothpaste, floating beneficiation, battery, coating, putty powder and papermaking.

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.
