Products Specifications:
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.

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.

6.      International Countertypes: Bentone®SD-2, Claytone®APA
