Modified Bentonite for Solvent -Organophilic Clay

Product Description

BK-127 is an organoclay 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 (@105ºC,2hrs)	Fineness through 200 mesh	Loss on Ignition ( @1000ºC )
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 95%ethanol, 95%methanol, 95%acetone or propylene carbonate) 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 rheology modifier 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
