BK-922

Products Specifications:

BK^®-922 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.
☆ Easy of incorporation. No need for polar activator or making pregel.
☆ Consistent in rheology and thixotropy development.
☆ Easy of dispersion with excellent fineness.
☆ 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.

2. Typical Properties:

Color	Appearance	Density	Moisture (@105℃,2hrs)	Fineness through 200 mesh	Loss on Ignition ( @1000℃ )
White	Free Flowing Powder	1.6g/cm³	≤3.5%	≥99%	≤38%

3. Typical Applications:

●Acrylic paint	●Silica paint
●Alkyd paint	●Inks(mineral oil)
●Anti-corrosion paint	●Inks(Nitro)
●Chlorinated rubber paint	●Adhesive
●Nitro lacquer	●Varnish
●Primer paint	●Lubricating grease
●Polyester paint

4.      Incorporations:
BK^®-922 belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activated organoclay, BK^®-922 does not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.
BK^®-922 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^®-922 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. For high thixotropy systems or thick film paints, the recommended levels are between 1%-2.7%.
