CR538 Chloride Process Rutile Titanium Dioxide | High-Weathering & Eco-Friendly TiO₂ Pigment
Product Overview
CR538 is chloride process, 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.
