In addition to specific requirements regarding viscosity, purity, pH value, and degree of substitution, the customer also has specific requirements for the powder appearance, as CMC (sodium carboxymethyl cellulose) is used as an additive in paint production.
In addition to specific requirements regarding viscosity, purity, pH value, and degree of substitution, the customer also has specific requirements for the powder appearance. CMC (sodium carboxymethyl cellulose) is used as an additive in paint production. Performance consistency becomes a decisive purchasing factor.
The customer outlined strict technical requirements.
The customer requires the following:
1. Good whiteness;
2. Good fineness;
3. Good solution transparency.
These requirements focused on whiteness, fineness, and solution transparency.
At the same time, pH value and substitution degree needed precise control. Conventional industrial processes no longer met expectations.
To meet these requirements, we adopted the following solutions:
1. Using food-grade refined cotton to produce industrial-grade CMC (sodium carboxymethyl cellulose), as food-grade refined cotton improves powder whiteness.CMC appears brighter and more consistent.
2. Using an 80-mesh vibratory sieve in the grinding process to obtain finer particles ensured uniform fineness across each production batch.
3. Through process adjustments, improving the degree of substitution, and controlling the pH value appropriately, the produced product exhibits good transparency in testing. It reduces haze while supporting smooth surface finishes.
Consequently, coatings achieve a more professional visual result.
This paint-grade CMC is fully customizable to meet specific application requirements. Customers can achieve optimal performance for different paint formulations.
