Applications
BERMOCOLL E 230 X is used for thickening and
stabilizing effects in mortars and other building
glues. BERMOCOLL E 230 X is also used as a
dispersing, binding and stabilizing agent for powder
materials dispersed in water.
The simultaneous viscosity increase is moderate.
Normal dosage is 0.4 - 0.8 % calculated on the dry
mortar weight.
BERMOCOLL E 230 X is also used in gypsum based crack
fillers. For this application, a suitable
concentration is about 1 %.
BERMOCOLL E 230 X is intended for dry mixing with
other powder materials and should not be used for
direct dissolving in water.
