BERMOCOLL E 320 G is a non-ionic, water soluble cellulose ether. It improves the consistency, the stability, and the water retention of water based products.
Bermocoll E 320 G
Ethyl hydroxyethyl cellulose
BERMOCOLL E 320 G is used to stabilize aqueous dispersions while avoiding problematic viscosity increase. Suitable dosage should be determined for each application, but is usually less than 0.5% of the total dispersion weight. BERMOCOLL E 320 G is used in latex paints for thickening and stabilizing effects. Normal dosage is 0.4 - 0.8 % calculated on the total paint weight. BERMOCOLL E 320 G is normally added as a ready stock solution. BERMOCOLL E 320 G is also used in aqueous solutions as an adhesive for standard quality wallpapers. 200 g (oz) of BERMOCOLL E 320 G in 6 litres (approx 1.5 gallon) of cold water will be just right for 12 paper rolls.Solutions should be prepared by addition of BERMOCOLL E 320 G at a moderate rate and with good agitation to avoid lump formation. After dispersion of the grains, the agitation speed may be reduced. The average time to attain a noticeable viscosity increase is 3-5 minutes, and the time for complete dissolving is 20-30 minutes.
