Product Overview: Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose (HEC) (CAS NO.: 9004-62-0) is a non-ionic water-soluble polymer. It is synthesized by reacting alkali-cellulose with ethylene oxide, offering:

• Powerful thickening and rheology control
• Excellent water retention and film formation
• Superior pigment dispersion and anti-settling ability
• Stable performance in wide pH ranges and compatibility with additives

Professional FAQ – Hydroxyethyl Cellulose for Paint

Expert Technical FAQ

1. What is Hydroxyethyl Cellulose (HEC) chemically?

HEC is an etherified, non-ionic, water-soluble derivative of cellulose, modified with hydroxyethyl groups. Its backbone retains β-1,4-glycosidic linkages, ideal for paint systems.

2. What is the recommended viscosity grade for paints?

Viscosity grades from 3,000 to 85,000 mPa·s (Brookfield, 2% solution at 20°C). Medium to high viscosity (25,000–65,000 mPa·s) is standard for architectural paints to maximize sag resistance and leveling.

3. How is HEC dosed in water-based paint formulations?

HEC is typically added at 0.2–1.0% of total formulation weight, depending on required consistency and rheology.

4. What is the significance of the hydroxyethyl cellulose cas number?

The CAS number 9004-62-0 uniquely identifies hydroxyethyl cellulose, ensuring regulatory and quality control traceability. Refer to PubChem for more.

5. Which standards govern quality testing?

ISO 758 (appearance), ASTM D2363 (identification), ASTM D2196 (viscosity), ASTM D1347 (moisture). Rigorous internal QC protocols are added for consistency.

6. What are advantages versus other cellulose ethers?

Compared with methyl cellulose or carboxymethyl cellulose, HEC offers higher water retention, non-ionic compatibility, and greater stability in presence of salts, surfactants, and biocides.

7. Is hydroxyethylcellulose for sale stable in alkaline paints?

Yes. HEC is stable and functional across pH 6–8.5, making it ideal for most emulsion and latex paints, including those with alkaline fillers and pigments.
