High-Quality Rutile Titanium Dioxide TiO2 R-215 from China Suppliers and Factory - Neutral Undertone, High Opacity
TiO₂ R-215 is a rutile titanium dioxide pigment. It appears as a white powder and features a high refractive index, strong hiding power, and high tinting strength, significantly improving whiteness, brightness, and gloss while providing a slight bluish undertone. The product is typically treated with inorganic coatings (such as alumina and/or silica) and organic surface treatments to enhance surface properties, enabling faster dispersion, more stable rheology (thixotropy), and lower oil absorption. It also delivers good weather resistance, heat resistance, and chemical resistance, helping reduce chalking and discoloration in outdoor applications. It is suitable for architectural and industrial coatings, powder coatings, coil and wood coatings, plastic masterbatches and compounded plastics (PVC, PP, PE, ABS, etc.), inks, papermaking, adhesives, and rubber products.
