titleOfInvention |
Treated inorganic pigments having improved dispersability and use thereof in coating compositions |
abstract |
The disclosure provides a coating composition comprising a treated inorganic core particle, having improved dispersability, prepared by a process comprising: heating a slurry comprising porous silica treated inorganic core particle and water at a temperature of at least about 90C, more typically about 93 to about 97C, still more typically about 95 to about 97C; and adding a soluble alumina source to the slurry while maintaining the pH at about 8.0 to 9.5 to form an alumina treatment on the porous silica treated inorganic core particle; wherein the treated inorganic core particle does not comprise dense silica or alumina treatments, and has silica present in the amount of about 7% to about 14% and alumina present in the amount of about 4.0% to about 8.0%; and wherein the particle to particle surface treatments are substantially homogeneous. |
