BERMOCOLL EHM 200 ED is an associative non-ionic,
water-soluble cellulose ether that improves the
rheological properties of water based paints.
Specifications
BERMOCOLL EHM 200 ED is a hydrophobically
modified
ethyl hydroxy ethyl cellulose.
Applications
BERMOCOLL EHM 200 ED is used as a thickener in all
types of latex paints, intended for interior as well
as for exterior use. BERMOCOLL EHM 200 ED improves
high shear viscosity, roller spatter, flow and
levelling. BERMOCOLL EHM 200 ED has a high resistance
to enzymatic degradation. Normal dosage is 0.3 - 0.5 %
calculated on the total paint weight.
In order to facilitate dispersion in water, BERMOCOLL
EHM 200 ED has been treated to give a pH-dependent
dissolving. It should be added to neutral or slightly
acid water. To speed up the dissolving process, pH
should be increased to above 8 by using alkaline
ingredients such as ammonia or alkaline pigment
dispersants.
If adjustment of the final paint viscosity is
necessary, a highly concentrated slurry either in
water or in an organic solvent should be used. It is
not recommended to add the product as a dry powder
after pigment grinding. Under the alkaline pH
conditions at that stage BERMOCOLL EHM 200 ED will
dissolve too rapidly with the risk of lump formation.
