Why Can the Nano-coating Protect Products Completely?

Nano-coating refers to the advanced technology of nano non-toxic coating. This high-tech nano-coating is not only non-toxic and harmless but also can slowly release a substance to degrade indoor formaldehyde, xylene, and other harmful substances.

The traditional surface coating technology can be used or modified to realize the nanomaterial composite coating. The addition of nanophase to the wear-resistant coating with high hardness can further improve the hardness and wear resistance of the coating and maintain high toughness.

Adding nanoparticles to the surface coating can reduce the friction coefficient, form self-lubricating materials and even obtain the super lubrication function. Besides, the application of nanomaterials in the coating can significantly improve the high-temperature resistance and oxidation resistance of the materials. For example, nano Ni-La203 coating is deposited on the surface of Ni, which prevents short circuit diffusion of nickel ions due to the action of nanoparticles, thus improving the growth mechanism and mechanical properties of the oxide layer.

The coating of nanomaterials can improve the corrosion protection ability of the matrix and achieve the purpose of surface modification and decoration. Nanoparticles can be added to paint or coating to further improve its protective ability, which is able to withstand the atmosphere, UV damage, so as to achieve anti-degradation, anti-discoloration, and other effects.

Nanomaterials coating has a wide range of optical properties and its optical transmission spectrum can be extended from the ultraviolet band to the far-infrared band. After being treated, the multilayer composite coating can be fluoresced in visible light. It is used in many optical applications, such as sensors and other devices. Nanomaterial coating was applied on the surface of various signage to become luminous and reflective signs; by changing the composition and characteristics of nano-coating, photochromic, thermochromic and electrochromic effects are obtained, and special anti-counterfeiting and identification methods are produced; 80nm yttrium oxide can be used as an infrared shield coating, reflecting heat efficiently; coating the surface of products such as glass with nanomaterials can reduce the transmission of light and heat transfer, resulting in thermal insulation; adding nanometer materials into the coating can play a flame retardant, heat insulation and fire prevention role.


The nanocomposite coating has excellent electromagnetic properties, and the coating formed by using the nanoparticle coating has a good wave absorbing ability, which can be used in the stealth coating. Nano titanium oxide, chromium oxide, iron oxide and zinc oxide particles with semiconductor properties were added to the resin to form a coating with good electrostatic shielding performance. The multilayer membrane system with nano-structure produces the giant magnetoresistive effect, which is expected to be used as a readout head in the storage system.
