- Applications
- BERMOCOLL EHM 200 is used as a thickener in all types of latex paints, intended for interior as well as for exterior use.
- BERMOCOLL EHM 200 improves high shear viscosity, roller spatter, flow and leveling.
- BERMOCOLL EHM 200 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 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 will dissolve too rapidly with the risk of lump formation.

Technical Details & Test Data
- Test Data
Bermocoll® EHM is a non-ionic associative cellulose-based polymer with enhanced enzymatic resistance. We developed it in order to improve the rheological properties in latex paints. Bermocoll® EHM combines the performance of low viscosity cellulose with high thickening efficiency.

Paint rheology, higher ICI viscosity
With equal dosage and Stormer viscosity (KU), Bermocoll EHM Extra achieves higher ICI viscosity than competitor products - demonstrating the robust and reproducible thickening character of our product. The higher ICI viscosity contributes to an improved film build and thus better coverage.
Safety & Health
- Safety Information
Like many industrial processed powdery materials, cellulose ether dusts are combustible and can cause dust explosions. Dust formation must be avoided or kept to a minimum. Care should be taken to prevent ignition from heat, spark, open flames or hot surface.
Packaging & Availability

- Packaging and Transport
BERMOCOLL EHM 200 is packed in polyethylene plastic bags. Net weight 20 kg. We recommend emptying the bags from the bottom. The empty bags can be re-cycled or burned.
Storage & Handling
- Storage Conditions
In unopened bags, BERMOCOLL EHM 200 can be stored for several years. In opened bags, the moisture content of BERMOCOLL EHM 200 will be influenced by the air humidity. At temperatures above 250°C (480°F), charring of BERMOCOLL EHM 200 will occur.
- Storage Conditions
- At high temperatures and in contact with an open flame, BERMOCOLL EHM 200 will burn slowly with the characteristics of cellulose.
