BERMOCOLL EHM 100 is an associative non-ionic,
water-soluble cellulose ether that improves the
rheological properties of water based paints.
Specifications
BERMOCOLL EHM 100 is a hydrophobically modified
ethyl hydroxy ethyl cellulose.
Applications
BERMOCOLL EHM 100 is used as a thickener in all types
of latex paints, intended for interior as well as
for exterior use. BERMOCOLL EHM 100 improves high
shear viscosity, roller spatter, flow and levelling.
BERMOCOLL EHM 100 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 100 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 100 will
dissolve too rapidly with the risk of lump
formation.
