BK^®-886B is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low to medium polarity.

1. Advantages:

 
鈽� High gelling efficiency over low to medium polarity organic liquids.
鈽� Ideal thixotropy ,anti-sagging,anti-sediment property.
鈽� Imparts particle suspension, preventing hard settling of pigment and fillers.
鈽� Exerts strong film reinforce action in organic binder systems.
鈽� Good dispersion performance.
鈽� Upgrade version of BK-886.

4. Incorportions:

BK^®-886B belongs to the conventional type of organoclay group, which requires mechanical 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.
Polar Activator: Dosage of polar activator ( such as propylene carbonate, 95%ethanol , acetone or 95% methanol) is 30%-50% by weight of BK^®-886B.

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.

 5. Recommended Levels:
The amount of BK^®-886B rheological additive required depends upon the type
of 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.
