Titanium Dioxide – Sulfate

Titanium dioxide obtained by the sulfate process is a white inorganic pigment based primarily on the rutile or anatase phase, produced from ilmenite or titanium slag through sulfuric acid digestion, hydrolysis, calcination, and controlled milling. It has a high refractive index (~2.7), which gives it high opacity and hiding power. It is characterized by good dispersibility, high whiteness, brightness, and tinting efficiency, making it suitable for architectural paints, industrial coatings, and enamels. Surface treatments (silica, alumina, or other oxides) improve its photographic stability, chalking resistance, durability, and compatibility with water-based and solvent-based systems. From a formulation standpoint, it allows for optimizing the PVC/CPVC ratio, improving coverage per square meter, and controlling the coating’s optical and rheological properties. Its cost-performance ratio positions it as a technically and economically efficient alternative for standard and medium- to high-performance formulations.
