R1931 is general use, multi-purpose rutile titanium dioxide pigment coated with dense ZrO2 & Al2O3 and special organic surface treatment. Products quality are very close to international advanced chloride process TiO2 products, having extreme whiteness and gloss, blue undertone, superfine particle size & narrow size-distribution, great UV-absorbing capacity, outstanding weatherability and chalk resistance, excellent hiding power and tinting strength, very good dispersion and stability. The products also show high gloss retention and tint retention, ensuring long term on exposure to weather conditions.
Applications:
Rutile Titanium Dioxide pigments R1931is high grade, general use, multi-purpose products, widely used in industries such as high grade indoor&outdoor coatings, interior and exterior latex paints, industrial coatings, powder coatings, plastics (PVC, PE, polystyrene and polyurethane etc.), masterbatch, PVC profile, rubber, high-grade printing ink and paper making, etc..
