Transparent coatings containing nano alumina can be widely used as protective coatings for car topcoats, transparent plastics, highly polished metal surfaces, wood and other flat materials to improve wear resistance and service life.

2. Corrosion resistant nano automotive coatings
Automobile electrophoretic paint is the first water-based paint developed. It is applied to the metal surface of the automobile after phosphating treatment. It is the first paint for automobile painting, and it is mainly responsible for anti-corrosion function. The electrophoretic paint has good corrosion resistance and uniform coating film, even in some "dead corners" such as contacts, caves, etc.

Effective in-situ encapsulation of inorganic nano-silica and other particles. Since the surface of inorganic silica and other nanoparticles is covered with a charged polymer film, the stability of the system is high and the compatibility with other polymer materials is good. The inorganic silica nano-powder composite water dispersion is used for the modification and enhancement of electrophoretic paint, forming a new nanocomposite manufacturing technology and practical nanomaterial products, which can improve the technical level and product quality of traditional industries.

3. Random and different color nano paint

Floppy car means that the car body looks different from different angles, and its core technology lies in the new nano-car paint.

The mica pearlescent pigment coated with nano-scale titanium dioxide and aluminum powder or nano-titanium dioxide is added to the coating, and the coating can produce a mysterious and changeable color effect. In particular, the rutile nano-TIO2 has an angular color change effect and is the most important and promising material in automotive metallic flash coatings. Nano TIO2's UV shielding is mainly based on scattering, and particle size is one of the important factors affecting the scattering ability. And will not cause environmental pollution.

4. Nano transparent thermal insulation coating

The main way to avoid overheating in the car is to make the heat from outside the car as little as possible and dissipate the heat in the car quickly to improve the thermal environment. The main measure to prevent heat inside the car is to coat a layer of highly reflective heat insulation paint on the car glass to reduce the absorption of solar radiation and reduce the heat transmitted into the car.

Studies have found that n2-type nano semiconductor materials with wide energy gaps, such as indium tin oxide (nano-ITO), antimony tin oxide (ATO), etc., have similar optical properties, that is, they have high reflectivity in the infrared region and visible light. It has a high transmittance in the ultraviolet region and a high absorption rate in the ultraviolet region. For example, the reflectivity of the American Ray-Ban car insulation film in the infrared region reaches 70% to 80%, and the visible light transmittance reaches 70%, so it is ideal Transparent insulation material.

5. Antibacterial nano car paint

Silver ions have antibacterial and bactericidal effects on 16 kinds of bacteria such as Escherichia coli and Staphylococcus aureus. It causes the dissolution of cell contents by destroying the bacterial cell wall, hindering the synthesis of beneficial bacterial metabolic enzymes, destroying genetic factors and causing bacteria to lose their Biological activity and so on to complete the sterilization process. Compared with ordinary silver ions, nano-silver has stronger bactericidal properties.


Nanotechnology is widely used. In addition to the above-mentioned functional automotive coatings, researchers have also tried to use nanotechnology to develop anti-ultraviolet and antistatic automotive coatings. Adding TiO2 to the car topcoat can improve the aging resistance of the car coating and greatly improve the scratch resistance.
