Rheological Additives (Organophilic Clay)

BK-923 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.
☆ 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.

2. Typical Properties: 
3. Typical Applications: 
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. The amount of BK-923 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.
