BK-923 is an organoclay for solvent-based systems of low, medium and high polarity.
1. Advantages:
☆ High gelling efficiency over low,medium and high 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.In suitable systems, it can reach 5μ or even less.
☆ 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.

3. Typical Application
4. Incorporations:
BK-923 belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activated organoclay, BK-923 does not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.
BK-923 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-923 rheological additive required depends upon the type of organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%-1.5% based on the total formulation weight.
