Application Information
  • Bermocoll® E 320 G is used to stabilize aqueous dispersions while avoiding problematic viscosity increase.
  • Suitable dosage should be determined for each application, but is usually less than 0.5% of the total dispersion weight.
  • Bermocoll® E 320 G is used in latex paints for thickening and stabilizing effects.
  • Normal dosage is 0.4 - 0.8 % calculated on the total paint weight.
  • Bermocoll® E 320 G is normally added as a ready stock solution.
  • Bermocoll® E 320 G is also used in aqueous solutions as an adhesive for standard quality wallpapers.
  • 200 g (oz) of Bermocoll® E 320 G in 6 litres (approx 1.5 gallon) of cold water will be just right for 12 paper rolls.
  • Solutions should be prepared by addition of Bermocoll® E 320 G at a moderate rate and with good agitation to avoid lump formation.
  • After dispersion of the grains, the agitation speed may be reduced.
  • The average time to attain a noticeable viscosity increase is 3-5 minutes, and the time for complete dissolving is 20-30 minutes.

Note

Bermocoll® E 320 G is a low viscosity grade of ethyl hydroxyethyl cellulose.

Safety & Health

Safety and Handling

At high temperatures and in contact with an open flame, Bermocoll® E 320 G will burn slowly with the characteristics of cellulose.

Packaging & Availability

Packaging and Transport
  • 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® E 320 G is packed in a polyethylene bag. 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 320 G can be stored for several years.
  • In opened bags, the moisture content of Bermocoll® E 320 G will be influenced by the air humidity.
  • At the temperatures above 250 °C (480 °F), charring of Bermocoll® E 320 G will occur.
