What are the applications of titanium dioxide in different coatings?
In recent years, with the rapid development of the coatings industry, people have higher and higher requirements for the performance of titanium dioxide. Not only do they require titanium dioxide to have very good dispersibility, but they also require titanium dioxide to have very good hiding properties. At the same time, they also have very high requirements for the impurity content of titanium dioxide. Under such high requirements, the widely used titanium dioxide has continuously improved its production technology, improved its performance, and expanded its application direction.
Among them, pigment-grade titanium dioxide has a high refractive index and strong tinting power, and has very outstanding advantages in both hiding power and dispersibility. For this reason, pigment-grade titanium dioxide has been widely used in coatings and papermaking. The proportion of pigment-grade titanium dioxide in coatings is the largest, among which rutile titanium dioxide is widely used in industry.
As decorative coatings
The pigment performance of pigment-grade titanium dioxide is very good, and modern people mostly choose white or light colors to decorate houses in house decoration. Therefore, pigment-grade titanium dioxide has been widely welcomed by people in house decoration. Not only that, pigment-grade titanium dioxide is also widely used in external coatings for ships, cars, etc.
As architectural coatings
Pigment-grade titanium dioxide plays a very important role in the production process of coatings, and titanium dioxide is mainly used in architectural coatings.
Make pure white coatings
Most white coatings on the market use a large amount of pigment-grade titanium dioxide in the manufacturing process.
Make colorful pattern coatings
Many pattern coatings on the market now cannot do without pigment-grade titanium dioxide in terms of color ratio or pattern, so pigment-grade titanium dioxide plays a very important role in the production of colorful pattern coatings. Pigment-grade titanium dioxide has also been widely used in automotive exterior paint because pigment-grade titanium dioxide has very good color and high brightness.
Make special functional coatings
Many high-temperature resistant coatings use pigment-grade titanium dioxide in the production process, and high-temperature resistant coatings are a type of special functional coatings, so pigment-grade titanium dioxide is an indispensable raw material in the production of special functional coatings.
Making conductive materials
Titanium dioxide can also be used to make conductive materials. Since the surface of pigment-grade titanium dioxide particles can form a coating, titanium dioxide can also be used in the production of antistatic materials.
Making core-coated titanium dioxide
Pigment-grade titanium dioxide can also be used to make core-coated titanium dioxide, which is also often used in the production of coatings.
Making slurry titanium dioxide
There is also a slurry titanium dioxide in the classification of titanium dioxide. It does not require very complicated processes or very high production costs during the production process. Therefore, slurry titanium dioxide is very popular in people’s production and life. Pigment-grade titanium dioxide is indispensable in the production process of slurry titanium dioxide, so pigment-grade titanium dioxide plays a very important role in the process of making slurry titanium dioxide.
UV shielding effect
Nano-grade titanium dioxide is widely used in the production of anti-UV coatings. In many places in people’s lives, it is necessary to avoid ultraviolet radiation. Therefore, it is very necessary to use nano-grade titanium dioxide with the function of UV shielding to make anti-UV coatings.
UV absorption effect
Nano-grade titanium dioxide can not only shield ultraviolet rays, but also absorb ultraviolet rays to a certain extent. Therefore, many light-colored coatings use nano-grade titanium dioxide in the production process. In addition, this titanium dioxide can also improve the weather resistance of building exterior walls.
Effect pigments
Rutile nano-grade titanium dioxide is widely used in automotive exterior paint. It can not only effectively cover the poor gloss of the exterior surface of the car, but also present people with more exquisite light effects. In addition, the application of rutile nano-grade titanium dioxide on the automotive topcoat allows people to see different light effects from different angles, thereby meeting people’s visual needs.
