Features & Advantages

Excellent Thickening Efficiency: Provides significant thickening at low addition levels, effectively controlling system viscosity.
Excellent Rheological Properties: Imparts pseudoplastic rheological properties to the solution, reducing viscosity under high shear, facilitating application (e.g., paint application). Viscosity quickly recovers and remains stable after shear is removed.

Good Water Retention: Effectively prevents water evaporation in building materials such as cement mortar and gypsum, extending open time and improving material strength and adhesion.

Broad pH Stability: Remains stable over a wide pH range (typically 2-12), making it suitable for a variety of formulations.

Nonionic Properties: Compatible with other nonionic, anionic, and cationic surfactants and polymers, and is not susceptible to precipitation with metal salts.

Excellent Film-Forming Properties: Forms flexible, transparent films that provide protection and gloss.

Dispersing and Protective Colloid Function: Helps stabilize emulsions and suspensions, preventing particle settling or aggregation. Resistance to mold and

enzyme degradation: The modified HEC has better resistance to microbial erosion.

Usage

Due to its versatility, hydroxyethyl cellulose (HEC) is widely used in the following industries:

Coatings Industry:
Water-based coatings: As a primary thickener, rheology modifier, and protective colloid, it provides excellent can opening, storage stability, spatter resistance, leveling, brushability, and helps prevent pigment settling.

Building Materials:
Cement mortar and gypsum mortar: As a water-retention agent and thickener, it improves workability, adhesion, and sag resistance.
Tile adhesives and putty powder: It improves workability and extends open time.

Petroleum Industry:
Drilling fluids and completion fluids: As a thickener, rheology control agent, and fluid loss additive, it enhances drilling efficiency and stability.

Household Chemicals:
Shampoos and conditioners: As a thickener, foam stabilizer, and improves feel and gloss.
Body washes and hand soaps: As a desired viscosity, enhancing the user experience.
Toothpastes and detergents: As a thickener and dispersant.

Pharmaceutical Industry:
Gels and Ointments: Acts as a thickener, excipient, and binder.
Eye Drops: Acts as a lubricant and thickener, increasing drug retention time on the ocular surface.

Paper Industry:
Sizing Agents and Coating Agents: Improves paper strength and printing performance.

Textile Industry:
Dyeing and Printing Auxiliary: Acts as a thickener and printing paste.
