Self-Acitivated Solvent-Based System Rheology Modifier Bentonite¹

Product Description BK-884 is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low to medium polarity. 1. Advantages: ☆ High gelling efficiency over low to medium polarity organic liquids,especially in aliphatic and aromatic solvent and the compound of above.☆ Easy of incorporation. No need for polar activator or making pregel.☆ Consistent in rheology and thixotropy development.☆ Excellent sag resistance and control of viscosity.☆ Produce gel with light color and high transparency.☆ Can be added at any step,even can be used in post-addition to correct the final viscosity of a certain batch. 2.

If addition is made with polar activator or after grinding, better performance can be expected. 5. Recommended Levels: The amount of BK-884 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%-2.0% based on the total formulation weight. 6. International Countertypes: Bentone?SD-1, Claytone?HY/AF, TIXOGEL? EZ-100.
