Abstract
An improved process is provided for making organosilicon compound surface-treated titanium dioxide pigments, involving aqueous treatment with alkyltrialkoxysilanes and dialkyldialkoxysilanes at mildly acidic pH values and in the presence of a monoprotic acid, and using heat from spray drying a high solids dispersion of filter cake and optionally from micronization as well to effectively promote the desired bonding of the alkyltrialkoxysilane and dialkyldialkoxysilane surface treatments with the pigment surface and thereby reduce the manufacturing cycle time for the pigments to a commercially practical cycle time. Further, improved gloss and tint strength aqueous coating compositions are provided comprising water, a film-forming component and certain of these same alkyltrialkoxysilane and dialkyldialkoxysilane surface treated titanium dioxide materials.
