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:

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.
