BERMOCOLL is a non-ionic, water soluble cellulose 
ether. It improves the consistency, the stability,
and the water retention of water based products.

Specifications
BERMOCOLL is a range of medium to high viscosity 
grades of ethyl hydroxy ethyl cellulose.

Applications 

BERMOCOLL is used in latex paints for thickening and 
stabilizing effects. Normal dosage in paints is 
0.2 - 0.5 % calculated on the total paint weight.

BERMOCOLL is used in cement-based tile fix and joint
mortars for improvement of workability, consistency,
water retention and adhesion. Normal dosage is
0.2 - 0.7 % calculated on the dry mortar weight.

BERMOCOLL is easily dispersed in cold water of pH7 
or less. BERMOCOLL 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 slight 
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.

Packaging and Storage 

BERMOCOLL is packed in multiply paper bags with an 
inner polyethylene bag. Net weight 20 kg (approx 44 
lbs). The empty bags can be recycled or burned. In 
unopened bags, BERMOCOLL can be stored for several 
years. In opened bags, the moisture content of 
BERMOCOLL will be influenced by the air humidity.

At the temperatures above 250°C (480°F), charring of 
BERMOCOLL will occur. At high temperatures and in 
contact with an open flame, BERMOCOLL will burn 
slowly with the characteristics of cellulose.
