As an important inorganic chemical material, titanium dioxide powder is widely used in paint industry, especially in the fields of architecture, automobile and industrial coatings. With its excellent hiding power, whiteness, weather resistance and chemical stability, titanium dioxide powder has become an irreplaceable component in paints and coatings, which plays a key role in improving the quality and service life of paint products.

Importance of Titanium Dioxide Powder in Paint Industry  

Covering power and whiteness

Ti02 powder has a very high refractive index, which can effectively reflect and scatter light, thus providing excellent hiding power and whiteness. This feature makes it an ideal white pigment in paint, which can not only improve the hiding power of paint, but also improve the overall brightness and color saturation. For industries that require color and surface quality, such as architecture and automobiles, titanium dioxide powder is undoubtedly the key material to improve the coating quality.

Weather resistance and durability

Because titanium dioxide powder has good chemical inertness and ultraviolet resistance, it can maintain its chemical stability after long-term exposure to natural environment, thus improving the weather resistance and durability of paint. This is very important for coatings of exposed buildings and outdoor facilities, which can effectively prolong the service life of coatings and reduce maintenance costs.

Environmental protection and health

Tio2 powder is a non-toxic and harmless material, which is harmless to human body and environment. This makes it popular under the background of modern environmental protection and rising health requirements, especially for indoor paint and coating of food contact materials. For example, tio2 powder is widely used for its good safety in scenes with high safety requirements such as children's room coatings and food packaging materials.

Application of Titanium Dioxide Powder in Different Types of Paints

Building coating

Architectural coatings are one of the main application fields of titanium dioxide powder in paint industry. Building exterior wall coatings not only need excellent hiding power and decorative effect, but also require strong weather resistance to resist the influence of external environment such as wind, rain and sun. titanium dioxide powder can effectively enhance the ultraviolet resistance and weather resistance of coatings, so that architectural coatings can still keep bright colors under long-term exposure. In addition, building interior wall coatings have high requirements for environmental protection, and the nontoxic characteristics of titanium dioxide powder meet the strict requirements for indoor air quality, so it occupies an important position in the field of building coatings.

Industrielle Beschichtungen

In industrial coatings, titanium dioxide powder not only provides decoration, but also has protective function. Industrial coatings are usually used in mechanical equipment, bridges, pipelines and other facilities, which are susceptible to corrosion in harsh environments. As a component of coatings, tio2 powder can not only provide high hiding power, but also enhance the corrosion resistance and durability of coatings and reduce the maintenance and replacement costs caused by corrosion. In addition, the appearance of nanometer titanium dioxide powder brings a new choice for industrial coatings, which can enhance the self-cleaning and antifouling properties of coatings and help to prolong the service life of equipment.

Automobile coatings

Automobile coatings have very high requirements on the hiding power, weather resistance and corrosion resistance of coatings. As a white pigment, titanium dioxide powder provides a lasting brightness and luster for the exterior of the car, which makes the car maintain a good appearance in various climatic conditions. At the same time, the ultraviolet resistance of ti02 powder can prevent the coating from fading or aging due to sun exposure, which is very important in the automobile industry. With the improvement of automobile aesthetics, the application scope of ti02 powder in automobile paint is expanding.

Functional coating

Functional coatings are one of the rapidly developing fields in recent years, such as antibacterial coatings, self-cleaning coatings and fireproof coatings. titanium dioxide powder is not only used as a pigment, but also can give the coating a variety of functions. Taking self-cleaning coatings as an example, nano-titania tio2 will produce photocatalytic effect in the sun, which can decompose organic pollutants attached to the surface, thus achieving self-cleaning effect. This characteristic is widely used in building exterior walls, billboards and glass curtain walls, which opens up a new space for the application of titanium dioxide powder in functional coatings.
