Product Description
R-228 is a sulphate-process rutile titanium dioxide. It is a non-toxic white powder with stable chemical properties. With inorganic coating and composite organic surface treatment, it delivers excellent dispersibility, low viscosity, superior blue-toned whiteness and hiding power in ink systems. It exhibits outstanding mirror gloss especially for surface printing inks and can be widely used in various ink formulations.
