Product Description

Cellulose ether HEC

1. Description
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.

Hydroxyethylcellulose is a white or off-white powder. The hygroscopic product is tasteless and odorless and it is available in two milling grade, i. E. As powder and fine powder.

2. Uses
HEC is mainly used as adhesive protective gelatin, thicker agent and stabilizing agent as well as additives to make emulsion, frozen gelatin, lotion, eye clear agent, suppository and tablets. HEC is also used for hydrophilic colloid, framework. Material, ready-made framework controlled release agent, and stabilizing agent in foodstuff.

Application Guide for the coatings industry:
High thickening effect
1)Hydroxyethyl Cellulose as latex paints, especially high-PVA coating, providing excellent coating properties. Paint a thick paste, it will not produce flocculation.
2) 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
1) Hydroxyethyl Cellulose aqueous solution of non-newtonian system, the performance of their solution have called thixotropy.
2) In the stationary state, the product is completely dissolved, the best coating system to maintain shape and cans thickening state.
3) In the dump state, the system to maintain moderate viscosity, making the product has excellent liquidity, and does not splash.
4) 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.
5) Finally, when the paint coating is completed, the viscosity immediately resume, paint immediate sag resistance.
Dispersion and solubility
1) 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.
2) After proper surface treatment of Hydroxyethyl Cellulose, a good adjustment of the dissolution rate and viscosity of the product increased speed.
Storage stability
1) Hydroxyethyl Cellulose has good mildew performance, provide sufficient time for the paint store. Effective prevention and treatment of pigments and filler sedimentation.

Application Guide for the cosmetics industry:
1) Cosmetics level Hydroxyethyl Cellulose has good mildew performance, thickening and rheology modification system function, good water retention, film formation, to give the final product full of visual effects and all the necessary application performance.
2) Hydroxyethyl Cellulose through the production process of fine extract, to minimize the residual solvent and residual on ignition.
3)After surface treatment of Hydroxyethyl Cellulose with cold water soluble, dry powder can be used directly to water. Good dispersion of the product in water to avoid the product knot groups, dissolved uneven happen. Final solution uniform, continuous and full.
4)Hydroxyethyl Cellulose thickening effect in addition to providing the necessary and rheological properties, but also has good color acceptance.

Oil industry Application Guide:
Applicated in cementing and oil drilling industries
1)Hydroxyethyl Cellulose thickening agent can be used as oil well workover 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.
2) Fluid in the well, Hydroxyethyl Cellulose is used as proppant carrier. These liquids can be easily through the process of cracking.
