Product : Rheological Additive BK-883B
Category : Rheological Additive for solvent based system(Organoclay)

BK-883B is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low,medium and high polarity.

1. Rheological additive 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.Rheological additive 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 propylene carbonate, 95%ethanol , acetone or 95% methanol) 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.

6.International Countertypes:

Bentone 52, Tixogel VP, Claytone HT.
