    Ruikang R-998 is a universal rutile titanium dioxide pigment. The Alumina and Zirconia surface treatment reduces the contact between TiO2 particles, resulting in excellent dispersion of R-998 in solvent-borne and water-borne systems and excellent durability. The organic-treatment during manufacture has further enhanced its dispersion.
