Product Description
BK®-922 is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low to medium polarity.
1. Advantages:
☆High gelling efficiency over lowto mediumpolarity organic liquids.
☆Easy of incorporation. No need for polar activator or making pregel.
☆Consistent in rheology and thixotropy development.
☆Easy of dispersion with excellent fineness.
☆Good anti-sagging property and anti-sediment property.
☆Can be added at any step,even can be used in post-addition to correct the final viscosity of a certain batch.

4. Incorporations:
BK®-922belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activated organoclay,BK®-922does not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.
BK®-922can 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®-922rheological 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%-1.5% based on the total formulation weight. For high thixotropy systems or thick film paints, the recommended levels are between 1%-2.7%.
