Applications & Uses

Coating End Applications
Product Applications
  • Bermocoll® EHM Extra can be used as a thickener in all types of latex paints, both in interior and exterior formulations.
  • Bermocoll® EHM Extra improves high shear viscosity, roller spatter, flow and leveling. Bermocoll® EHM Extra offers enhanced color and heat stability, good color acceptance with minimal flocculation even when the most problematic colorants are used.
  • Normal dosage is 0.1 to 0.8%, calculated on the total paint weight. In order to facilitate dispersion in water, Bermocoll® EHM Extra has been treated to give a pH-dependent dissolving.It should be added to neutral or slightly acid water. To speed up the dissolving process, pH should be increased to above 8 by using alkaline ingredients such as ammonia or alkaline pigment dispersants.If adjustment of the final paint viscosity is necessary, a highly concentrated slurry either in water or in an organic solvent should be used. It is not recommended to add the product as a dry powder after pigment grinding, due to the risk of lump formation at alkaline conditions.

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® EHM Extra is packed in polyethylene bags.
  • Net weight 20 kg bags are available.
  • We recommend emptying the bags from the bottom.
  • The empty bags can be recycled or burned.
