BERMOCOLL CST 347 is a non-ionic, water
soluble cellulose ether with enhanced enzyme
resistance. It improves the consistency, the
stability, and the water retention of water
based products.
Specifications
BERMOCOLL CST 347 is a medium viscosity grade
of ethyl hydroxyethyl cellulose.
Applications
BERMOCOLL CST 347 is used in latex paints for
thickening and stabilizing effects. Normal dosage
is 0.3 - 0.5 % calculated on the total paint weight.
BERMOCOLL CST 347 is easily dispersed in cold water
of pH 7 or less. BERMOCOLL CST 347 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.
