The stability of particles plays an essential role in manipulating the properties of their suspensions. Alkyl silanes and amines were applied to modify the kaolin surface in order to render the particles hydrophobic and dispersible in non-polar solvents. A Hammett indicator shows the surface of kaolin has strong acidic groups and the silanes, such as isobutyltrimethoxysilane (IBTMS), did not neutralise them, whereas the amines, such as hydrogenated tallow (HT) and a polyisobutyl chain based stabiliser (SAP), reacted with them.
