808 Dispersible Organic Bentonite Rheological Additive

808 rheological additive is a kind of newly developed high-purity dispersible self-activated organic ammonium montmorillonite organoclay, based on 801-D, With finer grain diameter, less than 30μm if dispersed completely, it is the rheological additive of paint, printing oil for the low-medium and some part of high polar solvent system of aliphatic hydrocarbon, esters, ketone. It can be dispersed self-activatedly without activator in the medium-high polar solvent systems like xylene, xylene-esters (such as butyl acetate), xylene-ketone (such as cyclohexanone).
