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.

2. Typical Properties:

Color	Appearance	Density	Moisture (@105℃,2hrs)	Fineness through 200 mesh	Loss on Ignition ( @1000℃ )
Light Yellow	Free Flowing Powder	1.7g/cm³	≤3.5%	≥98%	≤35%

3. Typical Applications:

●Acrylic paint	●Primer paint
●Alkyd paint	●Silica paint
●Anti-corrosion paint	●Solvent epoxy paint
●Bituminous paint	●Inks(mineral oil)
●Container paint	●Inks(Nitro)
●Industrial paint	●Nitro lacquer
●Marine paint

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.
