BERMOCOLL E 270 G is a nonionic, water soluble
cellulose ether. It improves the consistency,
the stability, and the water retention of water
based products
Specifications
BERMOCOLL E 270 G is a range of low viscosity
grades of ethyl hydroxyethyl cellulose.
Applications
BERMOCOLL E 270 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 270 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 270 G is
normally added as a ready stock solution.
BERMOCOLL E 270 G is also used in aqueous solutions
as an adhesive for standard quality wallpapers.
200 g (oz) of BERMOCOLL E 270 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 270 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.
