BERMOCOLL E 451 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 451 FQ is a range of medium to high
viscosity grades of ethyl hydroxy ethyl
cellulose.

Applications
BERMOCOLL E 451 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 451 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 451 FQ is easily dispersed in cold water
of pH7 or less. BERMOCOLL E 451 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.
