R6628 Titanium Dioxide

R‑6628 is a rutile titanium dioxide produced by the sulfate process, with its surface modified through inorganic coating of silicon and aluminum as well as organic treatment agents. It features uniform and moderate particle size distribution, and exhibits excellent whiteness, gloss, tinting strength, dispersibility, weather resistance, hiding power, and other characteristics.
R6628 titanium dioxide is a general‑purpose grade suitable for most application fields, especially for water‑based coatings, powder coatings, coil coatings, household appliance paints, PVC (pipes and profiles), water‑based inks, papermaking, and other areas.
25 kg/bag, in paper‑plastic composite bags. Alternative packaging options are also available upon customer request.
