Bermocoll® Flow

Bermocoll® Flow is a new type of hydrophobically modified cellulose ether for use as a rheology modifier in latex paints. Depending on the formulation, Bermocoll® Flow is intended to provide improved Flow and leveling and eliminate complex combinations of thickeners to achieve the optimal paint rheology profiles. In order to facilitate dispersion in water, Bermocoll® Flow 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 Bermocoll® Flow as a dry powder after pigment grinding, due to the risk of lump formation under the alkaline conditions at that stage.

Like many industrially 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. At the temperatures above 250°C (480°F), charring of Bermocoll® Flow will occur. At high temperatures and in contact with an open flame, Bermocoll® Flow will burn slowly with the characteristics of cellulose.

Bermocoll® Flow is packed in polyethylene plastic bags. Net weight 20 kg. We recommend emptying the bags from the bottom. The empty bags can be re-cycled or burned.

In unopened bags, Bermocoll® Flow can be stored for several years. In opened bags, the moisture content of Bermocoll® Flow will be influenced by the air humidity.
