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: 

Color	Appearance	Density	Moisture (@105ºC,2hrs)	Fineness through 200 mesh	Loss on Ignition ( @1000ºC )
Off White	Free Flowing Powder	1.7g/cm^3	≤3.5%	≥98%	≤35%

 
3. Typical Applications: 

Alkyd paint	Industrial paint
Anti-corrosion paint	Primer paint
Chlorinated rubber paint	Road paint
Container paint	Sealant

               
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.
