BERMOCOLL EHM 500

BERMOCOLL EHM 500
HIGH EFFICIENCY ASSOCIATIVE
CELLULOSIC THICKENER IN LATEX PAINT

BERMOCOLL EHM 500
gives the following
property improvements
to a latex paint
• High thickening efficiency
• Flowing consistency
• Good levelling
• Low spatter resistance
• Excellent color acceptance
• Minimizes the influence
of binders and colorants

Spatter resistance
Spatter is reduced considerably with BERMOCOLL EHM 500 compared
with high viscosity cellulose ethers. If further reduction in spatter is required,
BERMOCOLL EHM 300 is recommended.

Thickening efficiency
The efficiency of BERMOCOLL EHM 500
is normally considerably higher than
other high molecular weight cellulose
ethers and hydrophobically modified
cellulose ethers (fig 3).
BERMOCOLL EHM 500 is most suitable
for use with binders that have weak
association (low thickening effect) like
Vinylacrylics,VA/ethylene and VA/VeoVA.
However with acrylic latex and some
styrene acrylics the hydrophobic
interaction between the binders and
BERMOCOLL EHM 500 can be too
strong. An addition of 0.1 – 0.3%
of a non-ionic surfactant* can often
overcome these problems.
Influence of colorants
BERMOCOLL EHM 500 minimizes the
influence of colorants and the viscosity
drop is considerably lower compared
with other associative cellulose ethers
(fig 4).
