Rheological Additive BK-883B

BK-883B is an organoclay for solvent-based systems of low,medium and high polarity.



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.

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.

Chemical Activator

Methanol/H2O 30%-50% based on dry weight of BK-883B

Ethanol/H2O 95/5 40%-60% based on dry weight of BK-883B

Propylene Carbonate 35%-55% based on dry weight of BK-883B

Acetone/H2O 40%-60% based on dry 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.



RECOMMENDED LEVELS

The amount of BK-883B 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..
