1. outstanding whiteness; 2. excellent reducing power and covering power; 3. excellent dispersibility in both of water-based and oil-based atmosphere; 4. good weather resistance, heat resistance and light resistance and widely used.
Rutile TiO2 pigment is coated with zirconia and alumina in an inorganic manner and modified with special organic finishing agent on the surface. As a kind of multifunctional and general-purpose rutile TiO2 pigment with excellent whiteness, dispersibility, hydrophilicity and lipophilicity, it can be applied to a lot of fields including coating, plastic, ink and paper.
