1. Application in the coating industry
Pigment-grade titanium dioxide is non-toxic, good whiteness, high refractive index, strong achromatic power, large hiding power, good dispersion, stable physical and chemical properties, and has excellent optical and electrical properties. As a pigment, titanium dioxide can play a role in industrial production, such as coloring, brightening and improving product quality. Pigment-grade titanium dioxide with particle size between 200 ~ 400nm not only has the properties of electrostatic shielding, ultraviolet shielding, wear resistance and scratch resistance, but also can improve the adhesion of the coating and prevent the coating from sagging.
The surface of TiOEX - 7 series products is treated with a high-density inorganic coating, which has superior optical properties and presents brighter and clearer colors in the colored system of the blue phase. At the same time, titanium dioxide has strong weather resistance, covering power, achromatic power, and easy dispersion.
2. Application in the ink industry
Titanium dioxide/Titania is light-resistant, heat-resistant, weather-resistant, and hydrophobic, with a high refractive index, small and uniform particle size, good whiteness and light diffusion, strong coloring power and covering power, and good physical and chemical stability. Titania has become an indispensable white pigment in ink manufacturing, and also a necessary raw material for the deployment of many intermediate color ink products. The ink containing titanium dioxide is easy to disperse, durable and has good surface wettability. Adding the pigment-grade titanium dioxide to the water-based ink can make the ink strong in coloring, easy to disperse, and durable.
