Organoclay Tetraallkyl Ammonium Bentonite for Solvent-Based System

BK-300A 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 aromatic compounds.
☆ Ideal thixotropy property and anti-sediment property.
☆ High viscosity and excellent thickening property over a wide temperature range.
☆ Imparts particle suspension, preventing hard settling of pigment and fillers.
☆ Exerts strong film reinforce action in organic binder systems.
 
2. Typical Properties:  
3. Typical Applications:                  
4. Incorportions:
BK-300A belongs to the conventional type of organoclay group, which requires mechanical energy, shear forces applied with a goods dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.

Polar Activator: Dosage of polar activator (such as 95%ethanol, 95%methanol, 95%acetone or propylene carbonate) is 40%-60% by weight of BK-300A.

It is always recommended to determine the proper level of addition by experiment. Either defect or excess of chemical activator would result in poorer viscosity development.
  The amount of BK-300A rheology modifier required depends upon the type of organic system and the degree of thickening or Other properties desired. Addition levels are typically between 0.1%-3.0% based on the total formulation weight.
