Key Attributes

Bermocoll Prime has been developed as the next generation of cellulose ethers. It can be used in all types of latex paints ranging from low to high PVC. This new product is suitable for all types of interior and exterior paints and the advantages are most apparent in flat to semigloss finishes.

Performance advantages:

  • Advanced color compatibility and rheology control to enhance touch up properties. 
  • Optimal rheology profile.
  • Versatile.

 

Superior Color Stability and Excellent Color Development

Excellent color stability is achieved with Bermocoll Prime within a wide range of colorants and latex binders. Bermocoll Prime is designed with particular attention to color acceptance and color development and offers reliable color performance. This means that the color appears in a uniform homogenous manner and at the expected color strength. Color acceptance is related to the compatibility, distribution and stability of the colorant in the base paint.

 

Efficient Thickening and Good Stability at Low Addition Rate

Paints formulated with Bermocoll Prime show very stable and constant viscosity even when stored at elevated temperatures and are very versatile with respect to compatibility with different kinds of binders.

Applications

BERMOCOLL Prime 3500 can be used as a rheology modifier in all types of latex paints. BERMOCOLL Prime 3500 is recommended when high in-can as well as enhanced application viscosity is required. BERMOCOLL Prime 3500 offers enhanced color and heat stability, and provides excellent color acceptance even with colorants that are known to be problematic. Normal dosage is 0.2 - 0.7 % calculated on the total paint weight.BERMOCOLL Prime 3500 is easily dispersed in cold water of pH 7 or less.

 

BERMOCOLL Prime 3500 can form lumps when added to an alkaline liquid. To avoid this, it should be added as a ready stock solution, as 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 and Transport

BERMOCOLL Prime 3500 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
At high temperatures and in contact with an open flame, BERMOCOLL Prime 3500 will burn slowly with the characteristics of cellulose.
Storage Conditions

In unopened bags, BERMOCOLL Prime 3500 can be stored for several years. In opened bags, the moisture content of BERMOCOLL Prime 3500 will be influenced by the air humidity. At the temperatures above 250 °C (480°F), charring of BERMOCOLL Prime 3500 will occur.

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 surfaces.
