4. Incorportions:
BK®-886 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%-60% by weight of BK®-886.
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®-886 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.
