Product Description
BK-888 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.
☆ Ideal thixotropy property and anti-sediment property.
☆ Good viscosity and 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.
2. Typical Properties:
3. Typical Applications:
4. Incorportions:
BK-888 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-888.
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-888 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%-2.0% based on the total formulation weight.
