Bermocoll CST 349 Ethyl hydroxyethyl cellulose Akzo Nobel Rheology Modifier/ Thickener >> Cellulosic, non associative >> Hydroxyethyl cellulose (HEC) Coatings >> Waterborne BERMOCOLL CST 349 is a non-ionic, water soluble cellulose ether with enhanced enzyme resistance. It improves the consistency, the stability, and the water retention of water based products. Specifications BERMOCOLL CST 349 is a high viscosity grade of ethyl hydroxyethyl cellulose. Applications BERMOCOLL CST 349 is used in latex paints for thickening and stabilizing effects, particularly when high storage viscosity combined with low application viscosity is required. Normal dosage is 0.2-0.5 % calculated on the total paint weight BERMOCOLL CST 349 is easily dispersed in cold water of pH 7 or less. BERMOCOLL CST 349 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.
