  BK®-885 Rheological  Additive ----------------------------------------------------------------------------------------------------------------------   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:
