BK-138

Products Specifications:

BK^®-138 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.
☆ Produce reproducible thixotropic consistency over a wide temperature range.
☆ 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 (@105℃,2hrs)	Fineness through 200 mesh	Loss on Ignition ( @1000℃ )
white	Free Flowing Powder	1.7g/cm³	≤3.5%	≥98%	≤38%

3. Typical Applications:

●Alkyd paint	●Zinc-rich paint
●Anti-corrosion paint	●Inks(mineral oil)
●Bituminous paint	●Inks(Nitro)
●Chlorinated rubber paint	●Adhesive
●Marine paint	●Putties and sealant
●None solvent epoxy paint	●Lubricating grease
●Primer paint	●Oil drilling mud
●Road paint	●Waster water treatment
●Silica paint

4.      Incorporations:
BK^®-138 belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activated organoclay, BK^®-138 does not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.
BK^®-138 can be added at any point in the manufacturing process. If addition is made with polar activator or after grinding,better performance can be expected.

5.      Recommended Levels:
The amount of BK^®-138 rheological additive required depends upon the type of organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.1%-0.8% based on the total
formulation weight.
