BK®-883B is an
organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of
low,medium and high polarity.

4. Incorporations:
BK®-883B
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 40%-60% by weight of BK®-883B.
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®-883B
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.
