Bermocoll

Bermocoll EBS 481 FQ is a non-ionic, water soluble cellulose ether with enhanced enzyme resistance, which are delivered in the form of a whitish free-flowing powder of different particle sizes and it is almost odorless. Bermocoll improves the consistency, the stability, and the water retention of water-based products.

Specifications:

Bermocoll EBS 481 FQ is a high viscosity grade of ethyl hydroxyethyl cellulose.

Physical Specifications:

Appearance: Whitish powder

Particle size: 98 % < 500 μm

Water content: max 4 %

Salt content: max 5 %

Characteristics of aqueous solutions:

pH (1 % solution): 5-7

Surface activity: weak

Viscosity at 20°C-1 % solution: 4000–6000 mPa. s

Applications:

Bermocoll EBS 481 FQ is used in latex paints for thickening and stabilizing effects. Normal dosage of Bermocoll is 0.2 - 0.7 % calculated on the total paint weight.

Bermocoll EBS 481 FQ is easily dispersed in cold water of pH 7 or less. Bermocoll can form lumps when added to an alkaline liquid. To avoid this, Bermocoll 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 of Bermocoll after dispersion is influenced by the water pH. Alkaline additives can be used to speed up the dissolving process.

Safety, Packaging and Storage:

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.

Bermocoll EBS 481 FQ is packed in Polyethylene bags with Net weight of 20 kg. We recommend emptying the bags from the bottom. 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 EBS 481 FQ will be influenced by the air humidity.

At the temperature above 250° C (480° F) charring of Bermocoll EBS 481 FQ will occur. At high temperatures and in contact with an open flame, Bermocoll will burn slowly with the characteristics of cellulose.
