Dispersibility Both organoclays, BENTONE®54 and a market reference, were post added to a standard long oil alkyd paint formulation at a tip speed of 14 m/s and an active loading of 1 %. The easier dispersibility of BENTONE® 54 compared to the conventional competitive organoclay Figure 1. Figure 1: Dispersibility in long oil alkyd paint
Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite.
To enhance the efficiency of dispersibility, the study of composite dispersant systems has been undertaken. Zhang et al. [22] utilized ammonium citrate as an auxiliary dispersant to augment the dispersion effectiveness of Isobam 104. This resulted in improved rheological properties of the suspension, achieved through the synergistic …
