Performance advantages cellulose ethers versus synthetics
- Water retention - Bermocoll helps to retain the water within the paint film and also to delay it from penetrating into the substrate or evaporating. This gives an increased open time.
- Contribute to dispersion by improving flow during grinding.
- Contribute to stabilization (prevent flocculation) of pigments.
- Robust/Stable viscosity and creamy texture.
- Natural renewable polymer with chief component wood pulp or cotton linters.

- Application Information
- Bermocoll® E 230 FQ is used in latex paints, particularly for stabilizing the dispersion state with only moderate simultaneous viscosity increase.
- Normal dosage is 0.5 - 0.8 % calculated on the total paint weight.
- Bermocoll® E 230 FQ is easily dispersed in cold water of pH 7 or less.
- Bermocoll® E 230 FQ 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.

Safety & Health
- Safety and Handling
At high temperatures and in contact with an open flame, Bermocoll® E 230 FQ will burn slowly with the characteristics of cellulose.
Packaging & Availability
- Packaging and Transport
- Like many industrial processed powdery materials, cellulose ether dust 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.
- Bermocoll® E 230 FQ is packed in polyethylene plastic bags. Net weight 20 kg.
- We recommend emptying the bags from the bottom.
- The empty bags can be recycled or burned.
Storage & Handling
- Storage Information
- In unopened bags, Bermocoll® E 230 FQ can be stored for several years.
- In opened bags, the moisture content of Bermocoll® E 230 FQ will be influenced by the air humidity.
- At the temperatures above 250 °C (480 °F), charring of Bermocoll® E 230 FQ will occur.
