Bermocoll E 481 FQ Ethyl hydroxyethyl cellulose Akzo Nobel Rheology Modifier/ Thickener >> Cellulosic, non associative >> Hydroxyethyl cellulose (HEC) Coatings >> Powder Coatings Coatings >> Waterborne BERMOCOLL E 481 FQ is a non-ionic, water soluble cellulose ether. It improves the consistency, the stability, and the water retention of water based products. Specifications BERMOCOLL E 481 FQ is a range of medium to high viscosity grades of ethyl hydroxy ethyl cellulose. Applications BERMOCOLL E 481 FQ is used in latex paints for thickening and stabilizing effects. Normal dosage in paints is 0.2 - 0.5 % calculated on the total paint weight. BERMOCOLL E 481 FQ is used in cement-based tile fix and joint mortars for improvement of workability, consistency, water retention and adhesion. Normal dosage is 0.2 - 0.7 % calculated on the dry mortar weight. BERMOCOLL E 481 FQ is easily dispersed in cold water of pH7 or less. BERMOCOLL E 481 FQ 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 slight 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.
