BK-923
BK-887L
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.
