HEC
Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble cellulose ether, appearing as a white, free-flowing powder that dissolves in both cold and hot water. The product exhibits excellent resistance to acids and alkalis, as well as to electrolytes, providing stable thickening while also offering water retention, suspension, and anti-sagging properties; its aqueous solutions are clear and transparent. It is widely used in interior and exterior latex paints, construction adhesives, gypsum putties, personal care and household cleaning products, oilfield drilling muds, and other industries. HEC boasts superior dispersibility, resists caking, and ensures stable storage. Packaged in sealed 25 kg kraft paper bags, it should be stored in a cool, dry place.

Product Performance
- 1. Excellent solubility
It is soluble in both cold and hot water, with no high-temperature gelation. The surface-treated grades exhibit excellent dispersibility, preventing agglomeration and caking during feeding. - 2. Electrolyte-resistant and stable under acidic and alkaline conditions
It has a non-ionic structure, exhibits stable viscosity across a pH range of 2 to 12, and demonstrates excellent salt tolerance, making it suitable for high-salinity formulations. It is compatible with a wide range of inorganic salts and surfactants. - 3. Excellent rheological properties
The aqueous solution exhibits pseudoplastic behavior: it becomes thinner upon stirring and thickens when left undisturbed. It applies smoothly, resists sagging and splattering, offers excellent leveling, and is less prone to pinholes and bubbles. - 4. Multifunctional Additive
It simultaneously exhibits five key functions—thickening, water retention, suspension and dispersion, protective colloid formation, and film‑forming adhesion—while offering excellent storage stability; its antimicrobial‑degradation‑resistant formulation maintains consistent viscosity over extended periods.
Main application areas
- 1. Coatings Industry
Interior and exterior latex paints, textured stone coatings, textured finishes, and water-based industrial paints—used as a primary thickener to enhance application feel and stabilize pigment suspension. - 2. Building Materials Industry
801 construction adhesive, gypsum-based putty, leveling gypsum, and water-based tile adhesive help retain moisture, retard setting, enhance workability, and reduce cracking. - 3. Daily Chemicals
Shampoo, body wash, lotion, and transparent paste—formulated with a clear thickening system that remains free of cloudiness. - 4. Other Industries
Thickening agent for oil drilling fluids, sizing agent in textile processing, sizing agent in papermaking, pharmaceutical formulation, and protective colloid in polymer emulsion polymerization.
Mainstream models (by viscosity)
- Low viscosity (300–2000 mPa·s): Latex paint anti-settling agent, water-based ink, and thinning agents for daily chemical products
- Medium viscosity (3,000–10,000 mPa·s): Interior and exterior latex paint, construction adhesive, gypsum putty
- High viscosity (30,000–60,000 mPa·s): Drilling mud, high-water-retention mortar, and high-viscosity personal-care concentrate
