Coating End Applications
Product Applications
  • Bermocoll® EBS 481 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 481 FQ is easily dispersed in cold water of pH 7 or less.
  • Bermocoll® EBS 481 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.

Packaging & Availability

Packaging Type
Packaging 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.
  • Bermocoll® EBS 481 FQ is packed in Polyethylene 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 481 FQ 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 temperatures above 250 °C (480 °F), charring of Bermocoll® EBS 481 FQ will occur.
