High Viscosity Hydroxyethyl Cellulose for Construction Materials – Reliable Chemical Materials Supplier

Hydroxyethyl Cellulose (HEC) is a non-ionic, water-soluble cellulose ether derived from natural polymer cellulose through etherification with ethylene oxide. It features excellent thickening, water retention, and film-forming properties, making it a key additive in construction materials. As a professional chemical materials supplier integrating both manufacturing and trade, we offer high viscosity HEC with stable molecular structure and reliable rheological performance for global construction applications.

Technical Characteristics

Our hydroxyethyl cellulose products are available in various viscosity grades (30000–100000 mPa·s, measured by Brookfield RVT, 2% solution at 25°C). The substitution degree (DS 1.5–2.0) ensures optimal solubility and solution stability.
In alkaline or neutral systems, HEC shows excellent compatibility with inorganic fillers, latex emulsions, and other additives. As an efficient thickening agent, it forms a uniform colloidal solution, improving the viscosity and suspension of construction materials such as cement mortar, wall putty, and paint formulations.

Performance Advantages

1. Water Retention & Workability:
   The hydroxyl and ether groups in hydroxyethyl cellulose form hydrogen bonds with water molecules, effectively locking moisture inside the mixture. This improves open time and ensures even hydration of cementitious materials.

2. Rheology Control:
   As a thickening agent, high viscosity HEC provides excellent shear-thinning behavior, making mortar easy to spread under pressure while maintaining stability at rest. This enhances surface smoothness and reduces material sagging.

3. Chemical Stability:
   HEC is non-ionic, making it compatible with most cationic and anionic additives. It resists oxidation and enzyme degradation, ensuring long-term storage stability for construction materials formulations.

Applications

• Cement-based mortars and grouts

• Tile adhesives and wall putty powders

• Latex paints and coatings

• Gypsum-based plasters

• Self-leveling compounds
