R‑298

This rutile titanium dioxide is an odourless, non‑toxic white powder featuring stable chemical properties. With double‑layer inorganic coating and composite organic surface modification, it exhibits excellent dispersibility, superior whiteness, high brightness, great weather resistance, low abrasion loss and favourable levelling performance.
R‑298 is a high‑end universal‑grade rutile titanium dioxide manufactured via the sulphate process. Widely recognised among domestic and international sulphate‑process TiO₂ products, it is highly recommended for interior coatings, printing inks, plastics, papermaking and other related applications.
Standard packaging adopts 25 kg paper‑plastic composite bags, together with 500 kg and 1000 kg bulk jumbo bags. Custom packaging specifications can be provided according to customer requirements.
