BK-883
BK-887L
Products Specifications:

BK®-883 is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low to medium polarity.
 
1. Advantages:
☆ High gelling efficiency over low to medium polarity organic liquids,
especially in aromatic compounds.
☆ Ideal thixotropy property and anti-sediment property.
☆ High viscosity and excellent thickening property over a wide temperature range.
☆ Imparts particle suspension, preventing hard settling of pigment and fillers.
☆ Exerts strong film reinforce action in organic binder systems.

●Primer paint ●Waster water treatment

4. Incorportions:

BK®-883 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®-883.
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®-883 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.
