Abstract: Disclosed herein is a method for producing an aqueous titanium dioxide slurry. The method includes (a) providing an aqueous dispersion medium, and (b) dispersing titanium dioxide into the aqueous dispersion medium provided in step (a) to obtain a titanium dioxide slurry containing at least 65 wt.-% up to 85 wt.-% of titanium dioxide, based on the total weight of the thus obtained slurry, where step (b) is carried out by sole use of a non-milling mixing device and at least until the Hegman fineness of the titanium dioxide particles is below 8 μm. Further disclosed herein are a slurry obtained from the disclosed method, a coating composition containing the same, and a method for producing a coating and a thus coated substrate.
