Product Desciption
BK-922 is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems
of low to medium polarity.
1. Advantages:
High gelling efficiency over low to medium polarity 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.
2. Typical Properties:
3. Typical Applications:
4. Incorporations:
BK-922 belongs to the unconventional type of organoclays group, being an easy-to-disperse,
self-activated organoclay, BK-922 does not require a chemical (polar) activator to reach the
proper level of delamination of the organoclay platelet stacks.
BK-922 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-922 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%-1.5% based on the total formulation weight. For high thixotropy systems or thick film
paints, the recommended levels are between 1%-2.7%.
