Self-Acitivated Solvent-Based System Rheology Modifier Bentonite

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. Typical Properties:

Color	Appearance	Density	Moisture (@105ºC,2hrs)	Fineness through 200 mesh	Loss on Ignition ( @1000ºC )
Light White	Free Flowing Powder	1.65g/cm3	≤3.5%	≥98%	≤35%

3. Typical Applications:

Acrylic paint	Wooden paint
Adhesive	Varnish
Alkyd paint	Inks(Mineral oil)
Anti-corrosion paint	Inks(Nitro)
Chlorinated rubber paint	Nitro lacuquer
Primer paint	Sealant
Polyester paint	Lubricating grease
Road paint	Cosmetics
Silica paint

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

BK-884 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-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.
