BK-883 增稠流变剂

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.

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