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
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.
