Product Description
Name: Hydroxyethyl cellulose HEC
Formula: C29H52O21
CAS #: 9004-62-0
Synonyms: HEC, Natrosol 210HHX, Natrosol HIVIS 4465
Hydroxyethyl Cellulose (HEC) is a nonionic, fast hydrating, and ultra-high viscosity. HEC is used as viscosity and rheology modifier, water retention agent, stabilizer, and suspending agent in a varity of water-based fluid systems where a nonionic material is desired.
HEC is a non-ionic soluble cellulose ethers, hot and cold water can be dissolved, with thickening, suspension, adhesion, emulsification, film, water and protective colloid properties. Widely used in paints, cosmetics, oil drilling and other industries.

Application Guide for the coatings industry:
High thickening effect
Hydroxyethyl Cellulose as latex paints, especially high-PVA coating, providing excellent coating properties. Paint a thick paste, it will not produce flocculation.
Hydroxyethyl Cellulose has a higher thickening effect. can reduce the amount of formula to improve the economy, while improving the performance of paint abrasion.
Excellent rheological properties
Hydroxyethyl Cellulose aqueous solution of non-new to nian system, the performance of their solution have called thixotropy.
In the stationary state, the product is completely dissolved, the best coating system to maintain shape and cans thickening state.
In the dump state, the system to maintain moderate viscosity, making the product has excellent liquidity, and does not splash.
Brushing and roller coating, the product is easy to spread in the substrate. Facilitate the construction. At the same time, have a good anti-splash.
Finally, when the paint coating is completed, the viscosity immediately resume, paint immediate sag resistance.
Dispersion and solubility
Hydroxyethyl Cellulose are dissolved after a delay in processing, in the case of dry powder added, can effectively prevent caking. Ensure that HEC powder fully dispersed, began to hydration
After proper surface treatment of Hydroxyethyl Cellulose, a good adjustment of the dissolution rate and viscosity of the product increased speed
Storage stability
Hydroxyethyl Cellulose has good mildew performance, provide sufficient time for the paint store. Effective prevention and treatment of pigments and filler sedimentation
Coating industry recommend the use of various grades of Hydroxyethyl Cellulose:
Remark: S -> Surface treatment, SE -> Enzyme resistance
Oil industry Application Guide:
Applicated in cementing and oil drilling industries
Hydroxyethyl Cellulose thickening agent can be used as oil well work over fluid and cementing agent. Help to provide clarification of the low fixed content solution, thus greatly reducing the structural damage to the wells. The use of Hydroxyethyl Cellulose thickening fluid easily acids, enzymes or oxidants decomposition, greatly improving the ability to recover hydrocarbons.
Fluid in the well, Hydroxyethyl Cellulose is used as proppant carrier. These liquids can be easily through the process of cracking.
Hydroxyethyl Cellulose configuration using drilling fluid, based on its low solids content, can effectively increase drilling stability. These properties can be used to inhibit the fluid medium to high hardness of the rock and heavy shale or shale drilling.
Reinforcement in the cement operations, Hydroxyethyl Cellulose slurry can reduce the hydraulic friction, the loss of rock to minimize water loss.
Oil industry use grade Hydroxyethyl Cellulose:
