Bermocoll CST 170 Ethyl hydroxyethyl cellulose Akzo Nobel Rheology Modifier/ Thickener >> Cellulosic, non associative >> Hydroxyethyl cellulose (HEC) Coatings >> Waterborne BERMOCOLL CST 170 is a non-ionic, water soluble cellulose ether. It improves the consistency, the stability, and the water retention of water based products. Specifications BERMOCOLL CST 170 is a low viscosity grade of ethyl hydroxyethyl cellulose. Applications BERMOCOLL CST 170 is used for thickening and stabilizing effects in latex paints. Normal dosage is 0.4 - 0.8 % calculated on the total weight. BERMOCOLL CST 170 is easily dispersed in cold water of pH 7 or less. BERMOCOLL CST 170 can form lumps when added to an alkaline liquid. To avoid this, it should be added as a ready stock solution, as a slurry in slightly acid water or in an organic solvent, or as a dry mix with other powder materials. The dissolving time after dispersion is influenced by the water pH. Alkaline additives can be used to speed up the dissolving process. Non-ionic, low viscosity grade of ethyl hydroxyethyl cellulose.
