BERMOCOLL is a non-ionic, water soluble cellulose
ether. It improves the consistency, the stability,
and the water retention of water based products.
Specifications
BERMOCOLL is a range of medium to high viscosity
grades of ethyl hydroxy ethyl cellulose.
Applications
BERMOCOLL 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 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 is easily dispersed in cold water of pH7
or less. BERMOCOLL 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.
