Product Description
BK-885 is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of medium to high polarity.
1. Advantages:
☆ High gelling efficiency over medium to high polarity organic liquids, especially in xylene, heavy aromatics, butyl acetate, ketone, alcohol and compound of above.
☆ Produce reproducible thixotropic consistency 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. Incorporations:
BK-885 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 30%-60% by weight of BP®-183-D.
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.
5. Recommended Levels:
The amount of BK-885 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: Tixogel® VZ, Bentone®27
