Applications
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.
