BERMOCOLL CST 295 is a non-ionic, water soluble
cellulose ether. It improves the consistency,
the stability, and the water retention of water
based products.
Specifications
BERMOCOLL CST 295 is a high viscosity grade
of ethylhydroxy ethyl cellulose
Applications
BERMOCOLL CST 295 is used in latex paints for
thickening and stabilizing effects. Normal dosage
in paint is 0.2 - 0.5 % calculated on the total
paint weight.
BERMOCOLL CST 295 is easily dispersed in cold water
of pH 7 or less. BERMOCOLL CST 295 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 slightly 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.
