R6618(T) Titanium Dioxide

This product is a sulphate‑process rutile titanium dioxide, appearing as non‑toxic white powder with stable chemical properties. Its surface is coated with zirconia and alumina inorganic layers followed by organic surface modification. It boasts excellent whiteness, strong hiding power, high gloss, superior weather resistance, narrow particle size distribution and outstanding dispersibility.
R‑6618 (T) titanium dioxide is a multi‑functional general‑purpose grade suitable for most application fields, especially coatings, paints, printing inks (solvent‑based, tin‑printing), leather, color pastes & color chips, plastics, rubber and other industries.
25 kg per paper‑plastic composite bag. Custom packaging can be provided in accordance with customer requirements.
