Hydroxyethyl cellulose HEC
use: 1, pharmaceutical 2, latex paint, polymer 3, oil drilling 4, daily chemical,5.construction    Description: tasteless, odorless, non-toxic white or light yellow powder particles flow easily; non-ionic water-soluble polymer Product properties: a thickening, binding, emulsification, dispersion, stability, and to maintain moisture to form a film and provide protective colloid effect, soluble in cold water and hot water, can provide a wider range of solution viscosity; is a high concentration of electrolyte solution thickener; water capacity than twice as methyl cellulose, has a good flow of regulatory.  Technical specification Item Grade Viscosity(mPa.s)(2% solu., *0°C) **0,***0,***0,****0,****0,****0,*****0 Loss on drying (%) ≤3.0 Residue on ignition(%) ≤0.4 Ph 6.**8.5 Heavy Metals(ppm) ≤2.0 Lead (ppm) ≤*0    2. 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-newtonian 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 Headcel 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: Specification Viscosity (2% solution, *5°C) HE***0S ******0mPa.s HE****0S ********0mPa.s HE****0SE ********0mPa.s HE*****0S **********0mPa.s HE*****0SE **********0mPa.s HE******0S **********0mPa.s HE******0SE **********0mPa.s HE******0S ***********0mPa.s HE******0SE ***********0mPa.s HE******0S ************0mPa.s HE******0SE ************0mPa.s Remark: S —> Surface treatment, SE —> Enzyme resistance Application Guide for the cosmetics industry:  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 .
 Hydroxyethyl Cellulose through the production process of fine extract, to minimize the residual solvent and residual on ignition.
 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.Hydroxyethyl Cellulose thickening effect in addition to providing the necessary and rheological properties, but also has good color acceptance.
