BK-886

Code: 08-51-001

Rheological Additive

BK- 886 is an organoclay (tetraalkyl ammonium bentonite) for solvent-based systems of low to medium polarity.


Advantages

  • High gelling efficiency over low to medium polarity organic liquids.
  • Ideal thixotropy, anti-sagging, anti-sediment property.
  • Imparts practice suspension, preventing hard settling of pigments and fillers.
  • Exerts strong film reinforce action in organic binder systems.
  • Good dispersion performance.

Incorporations


BK-886 belongs to the conventional type of organoclay group, which requires mechanical energy, shear forces applied with a good 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, acetone or propylene carbonate) is 30%-60% by weight of BK-886.

It is always recommended to determine the proper level of adittion by experiment. Either defect or excess of chemical activator would result in poorer viscosity development.
