BK-127
Products Specifications:
BK®-127 is an organoclay (tetraallkyl ammonium bentonite) for
solvent-based systems of high polarity.
 
 
1.      Advantages:
 
High gelling efficiency over high polarity organic liquids, especially in aromatic, alcohol, ketone, and the compounds of above.
Produce reproducible thixotropic consistency 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.      Incorporations:
BK®-127 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 30%-50% by weight of BK®-127.
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®-127 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®27, Tixogel® VZ
