R219 is titanium dioxide pigment for coatings, manufactured by sulphate process. Appearance is white powder, insoluble in water, non-toxic, chemically extremely stable. It has excellent pigment properties, such as good whiteness, brightness, hiding power, high tint reducing power and ease of dispersion, excellent weathering resistance and chalking resistance
Widely used in high-quality water-based and solvent-based coatings, interior and exterior architectural coatings, powder coatings, coil coatings, furniture coatings.
