| 15H | 1% Soln ≥1800 | ≥1.50 | ≥95.0 | ≤10% | ||
| 18H | 1% Soln ≥1000 | ≥1.80 | ≥95.0 | ≤10% | ||
Applications of Paint Grade CMC
- Thickening and Rheology Adjustment: As a thickener in the paint industry, CMC can adjust the viscosity and rheological properties of paints, improving their coatability and flowability.
- Emulsion Stability: CMC Paint Grade acts as an emulsion stabilizer in water-based paints, ensuring uniform dispersion of paint particles and improving paint stability and coating effect.
- Anti-settling and Dispersibility: Due to its colloidal water-retaining properties, sodium carboxymethyl cellulose can prevent pigment sedimentation and aggregation in paints, maintaining pigment dispersion and improving color uniformity and stability.
Advantages of Sodium Carboxymethyl Cellulose Paint Grade:
1. Natural and Renewable: Sodium carboxymethyl cellulose is made from natural cellulose, making it renewable and environmentally friendly.
2. Good Solubility: Sodium carboxymethyl cellulose has good solubility in water, facilitating its addition and mixing in industrial production.
3. Wide Range of Adjustable Properties: The dosage and processing method of sodium carboxymethyl cellulose can be adjusted to regulate its function and performance in different industrial fields, meeting diverse production needs.
4. Good Stability: Sodium carboxymethyl cellulose exhibits good stability in acidic and alkaline environments and is not easily affected by external conditions.
5. Multifunctionality: Sodium carboxymethyl cellulose has multiple functions in various industrial fields, such as thickening, emulsion stabilization, rheological adjustment, and improved paper strength, providing convenience and benefits for industrial production.
