Description

BK-883C is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low,medium and high polarity.

1. Advantages:
☆ High gelling efficiency over low, medium and high polarity organic liquids, especially in 200#solovent oil, coal tar, 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.

2. Typical Properties:

Color	Appearance	Density	Moisture (@105ºC,2hrs)	Fineness through 200 mesh	Loss on Ignition ( @1000ºC )
Light Yellow	Free Flowing Powder	1.69g/cm³	≤3.5%	≥98%	≤36%

3. Typical Applications:

Anti-corrosion paint	Zinc-rich paint
Marine paint	Inks(mineral oil)
Primer paint	Inks(Nitro)
Chlorinated rubber paint	Adhesive
Alkyd paint	Putties and sealant
None solvent epoxy paint	Lubricating grease
Bituminous paint	Road paint

4. Incorporations:

BK-883C 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 40%-60% by weight of BK-883C.
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-883C 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.
