805 Organic Bentonite Rheological Additive

805 rheological additive is a kind of organic ammonium montmorillonite organoclay, is a kind of white powder with high transparency and good performance in constancy reinforcement, thixotropic and anti-depositing. It has gelatin capability to medium to high polarity systems as well as various hydrogenated oil and composite linking substances. It is equivalent to Bentone 27.

Usage:

805 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 805.

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.


Dosage

The amount of 805 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%-2.0% based on the total formulation weight.
