Features & Benefits
- CASE Ingredients Features
- 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.
Performance advantages: Low viscous
- Maximum open time/water retention.
- Leveling.
- High application (ICI) viscosity.

- Applications
- BERMOCOLL EBS 451 FQ is used in latex paints for thickening and stabilizing effects, particularly when high storage viscosity combined with low application viscosity is required. Normal dosage is 0.2 - 0.7 % calculated on the total paint weight.
- BERMOCOLL EBS 451 FQ is easily dispersed in cold water of pH 7 or less.
- BERMOCOLL EBS 451 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 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 and Transport
BERMOCOLL EBS 451 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 Conditions
In unopened bags, BERMOCOLL EBS 451 FQ can be stored for several years. In opened bags, the moisture content of BERMOCOLL EBS 451 FQ will be influenced by the air humidity. At the temperatures above 250°C (480°F), charring of BERMOCOLL EBS 451 FQ will occur.
- Storage Conditions
- At high temperatures and in contact with an open flame, BERMOCOLL EBS 451 FQ will burn slowly with the characteristics of cellulose.
