It is therefore believed that the nano ZnO particles effectively are disposed around and associated with the TiO2 particle so that {HEAD ~ the efficiency} of {TAIL ~ the TiO2 particles} arrangement increases; i.e., the overall stability of TiO2 pigment particles on drying is improved, thus improving properties such as tint strength and hiding power
