    ◎Description

    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.


    ◎Key Features

    • Manufacturing consistency   • Excellent chalk resistance

    • Excellent gloss retention     • Superior dispersibility

    • High tint strength and gloss


    ◎Application

    Ruikang R-998 is a general-purpose interior pigment recommended use in coatings, plastics, inks, papers,etc.
