BK-883B is an organoclay for solvent-based systems of low,medium and high polarity.
1. Advantages:
☆ High gelling efficiency over low, medium and high polarity organic liquids, especially in 200#solovent oil, coal tar, aromatic compounds.
☆ Produce reproducible thixotropic consistency over a wide temperature range.
☆ 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.

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 95%ethanol, 95%methanol, 95%acetone or propylene carbonate)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.
