R6668 is a rutile titanium dioxide which was surface modified by a zirconium aluminum inorganic coating and a new dispersant organic treatment agent. It has average particle size distribution, low viscosity, blue undertone, good dispersion, high whiteness and high hiding power properties. It is especially used in color paste and sheet, Tin-printing ink, coil coating, woodware paint, etc.
Application Areas: Color paste and sheet, Ink, Woodware paint
Packing: 25kg paper bag 500kg and 1000kg bag
