Very high solids TiO2 slurries

摘要

The present invention discloses high solids slurries of anatase titanium dioxide pigment comprising greater than about 75% by weight of anatase TiO2 pigment dispersed in water. A process for producing the slurries of the present invention is disclosed which comprises the steps of a) dry milling the anatase titanium dioxide pigment, preferably by pressure rolling, and b) mixing the dry milled pigment with water in the presence of an acrylic acid dispersant.
