Inorganic material particles are dispersed in an aqueous medium with surface charge control additives, so as to obtain a moderately stable liquid slurry or pigment spray. The dispersion can be used to prepare fully formulated compositions. Products formulated using the aqueous dispersion can be prepared to achieve the same performance as products comprising an inorganic material dispersed using conventional polyelectrolyte pigment dispersants, but with higher levels of inorganic material, or superior performance characteristics with analogous levels of inorganic material. |
