BK-388 belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activated organoclay, BK-388 does not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.
BK-388 can be added at any point in the manufacturing process. If addition is made with polar activator or after grinding,better performance can be expected.
Polar Activator: Dosage of polar activator (such as propylene carbonate, 95%ethanol, 95%acetone or 95% methanol) is 20%-30% by weight of BK-388.
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-388 rheology modifier required depends upon the type of organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%- 0.8% based on the total formulation weight.
