Titanium dioxide coating has many excellent properties, such as high refractive index, strong achromatic power, large covering power, good dispersion, good whiteness, non-toxic and so on, which are incomparable with other white pigments. As soon as it came into the market, it quickly replaced the traditional white pigments, such as lead white, zinc white, lithopone, and became the king of white pigments. Since it is the best covering pigment and decolorizing pigment for white and light colors, it is widely used in fields such as paints, plastics, paper, rubber and inks that require white or light colors.
Among all the applications of titanium dioxide, titanium dioxide coatings are used the most. Titanium dioxide coating is a viscous suspension composed of base materials, pigments, fillers, solvents and additives. The pigment in the paint has a certain hiding power. It can not only cover the surface of the object to be coated, but also impart bright colors to the coating film to achieve aesthetics and decoration. No matter it is solvent based coating or water-based coating, the role of titanium dioxide coating is not only to cover and decorate, but also to improve the physical and chemical properties of the coating, enhance the chemical stability, so as to improve the covering power, achromatic power, corrosion resistance, light resistance, weather resistance, and enhance the mechanical strength and adhesion of the film. In addition, it can also prevent cracks, prevent the penetration of UV and water, so as to delay the aging and prolong the film life.
Titanium dioxide coatings are widely used in coatings. They are used in coatings for construction, automobiles, ships, furniture, household appliances, coil coating, toys and daily necessities. In the coating industry, architectural coatings consume the most titanium dioxide coatings, followed by coatings for automobiles, ships, railway vehicles, and furniture. Due to the excellent performance of rutile titanium dioxide coating compared with Ruiqin titanium dioxide coating, rutile titanium dioxide coating is selected as high weather resistance coating for ships, bridges, automobiles, buildings and other indoor and outdoor applications. At present, rutile titanium dioxide coatings have more than 70% of the titanium dioxide coatings. The coating industry not only needs more titanium dioxide coatings in quantity, but also has higher requirements on variety and quality.
