Bentonite is a clay mineral, which can be used in many industries due to its unique chemical and physical properties. In this study, a rheological agent was obtained from Yazi{dotless}r region bentonite in order to produce solvent-based paint. This material is a mixed type bentonite (Na/Ca ratio is about 0.35) which consists of 86% montmorillonite and some impurities such as quartz, calcite, feldspar and biotite. Different techniques such as agitation, classification and decantation were applied to remove the impurities from the sample for obtaining the pure Na-bentonite. Then, ion exchange process was applied to the material with the quaternary ammonium salts at certain temperature and period. At the end of these tests, a specific organo-clay (rheological agent) was obtained. The properties of the obtained product was compared to other industrial trade mark products. © 2000 Elsevier B.V.
