BK®-884A is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low,medium and high polarity.
1. Advantages:
¡î High gelling efficiency over low,medium and high polarity organic liquids,especially in aliphatic and aromatic solvent and the compound of above.
¡î Easy of incorporation. No need for polar activator or making pregel.
¡î Consistent in rheology and excellent thixotropy development.
¡î Excellent sag resistance and control of viscosity.
¡î Produce gel with light color and high transparency.
¡î Can be added at any step,even can be used in post-addition to correct the final viscosity of a certain batch.
¡î Upgrade version of BK-884.

4. Incorporations:
BK®-884A belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activated organoclay, BK®-884A does not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.
BK®-884A 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®-884A 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%-2.0% based on the total formulation weight.
