1. Advantages:
☆High gelling efficiency over high polarity organic liquids, especially inaromatic,alcohol, ketone,and the compounds of above.
☆Produce reproducible thixotropic consistency over a wide temperature range.
☆Imparts particle suspension, preventing hard settling of pigment and fillers.
☆Exerts strong film reinforce action in organic binder systems.

4. Incorporations:
BK®-127 belongs to the conventional type of organoclay group, which requiresmechanical energy, shear forces applied with a goods dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of
the organoclay platelet stacks.
the organoclay platelet stacks.
Polar Activator:Dosage of polar activator (such as 95%ethanol, 95%methanol, acetone or propylene carbonate) is 30%-50% by weight of BK®-127.
It is always recommended to determine the proper level of addition by experiment. Either defect or excess of chemical activator would result
in poorer viscosity development.
in poorer viscosity development.
5. Recommended Levels:
The amount of BK®-127 rheological additive required depends upon the typeof organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%-2.0% based on the total formulation weight.
