BERMOCOLL E 411 G 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 411 G is a medium viscosity grade
of ethyl hydroxyethyl cellulose.
Applications
BERMOCOLL E 411 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 411 G is used in latex paints for
thickening and stabilizing effects. Normal dosage
is 0.3-0.5 % calculated on the total paint weight.
BERMOCOLL E 411 G is normally added as a ready stock
solution.
Solutions should be prepared by addition of BERMOCOLL
E 411 G at a moderate rate and with good agitation of
the water 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.
Improves the consistency, the stability, and the water retention of water based products. Nonionic, range of medium viscosity grades of ethyl hydroxyethyl cellulose. Weak surface activity.
