Paint Grade CMC

Description:

As a professional supplier of optical performance coating additives, our paint grade sodium carboxymethyl cellulose (CMC) is a green water-soluble polymer derived from natural cellulose. It is specifically designed to meet the stringent requirements of the modern coatings industry for rheology control, stability, and workability, making it a key additive for producing high-quality water-based coatings and putty products.

Characteristics:

High Thickening Efficiency: Even a small addition significantly increases the viscosity of the coating, effectively improving application feel and preventing sagging during application.

Excellent Water Retention: Effectively locks in moisture within the coating, extending the “open time” to allow sufficient leveling during drying, reducing brush marks, and ensuring uniform absorption of the coating by the substrate.

Outstanding Suspension and Anti-Settling Properties: During storage, it effectively suspends pigments and fillers, preventing hard settling and ensuring easy stirring and consistent color when the container is opened.

Good Enzyme Resistance: Specially treated enzyme-resistant grade products are available, effectively preventing viscosity loss due to microbial degradation and ensuring stable performance throughout the coating’s shelf life.

Excellent Compatibility: Demonstrates good compatibility with common coating components such as emulsions, pigments, fillers, dispersants, and film-forming aids.

Recommended Model: PM6, PH1000, PH3000, PH5000, PH6000
