Product Overview:

AF (Anti-Fingerprint) processing uses dry or wet techniques to create an ultrathin anti-fingerprint coating on the material surface, effectively preventing fingerprint residue while maintaining a smooth, easy-to-clean surface. Depending on the process, PVD (Physical Vapor Deposition), spray coating, and dip coating can be chosen.

Process Description:

(1) PVD Processing: In a high-vacuum environment, the source material is volatilized using electron gun heating or resistive evaporation heating, etc., forming particles such as atoms, molecules, or ions. These particles combine with the substrate through physical/chemical reactions to form a uniform nanometer-thin film.

(2) Spray Coating: The AF functional liquid is dispersed into uniform and fine mist droplets by a spraying device and applied to the substrate surface. It is then processed at a certain temperature to form a uniform nano-coating.

(3) Dip Coating: The substrate is immersed in the AF functional liquid for a certain time, allowing the substrate surface to adhere to a certain amount of AF functional liquid. It is then processed at a certain temperature to form a uniform nano-coating.

Characteristics:

Excellent hydrophobic and oleophobic properties: The AF coating has good water and oil resistance, reducing the adhesion of stains on the substrate surface and making maintenance convenient.

Strong wear resistance: The AF coating has strong adhesion to the substrate, is wear-resistant, and has a long service life.

Good chemical stability: The AF molecular chemical bond energy is high, making it difficult to decompose and resistant to corrosion from common chemicals.

Good smoothness: The AF coating has a low dynamic coefficient of friction, improving the smooth touch feeling of the substrate surface.

Application Areas:

AF technology is widely used in the following areas: electronic displays of electronic products such as smartphones, tablets, and televisions; various camera lenses; car windows, building glass; and metal surfaces, etc. By reducing fingerprint residue, it improves visual experience and durability, making it an indispensable key technology in modern production.

PVD is suitable for small-sized components with high appearance requirements and irregular shapes.

Spray coating is suitable for large-sized planar components.

Dip coating is suitable for larger components with irregular shapes.

Product Overview:

An ultra-hydrophilic coating is formed on the material surface through dip coating, which can effectively prevent water vapor from condensing into droplets, keeping the vision clear.

Principle Introduction:

Under normal circumstances, condensed water will condense into a layer of fine water droplets adhering to the transparent interface. Light is scattered and irregularly refracted at the water droplet interface, resulting in blurred visual imaging, which is “fogging”. On the ultra-hydrophilic interface, however, condensed water will automatically spread into a uniform, thin water film, allowing light to pass through along the same refractive path without affecting visual imaging.

Process Description:

By immersing the substrate in the anti-fogging liquid for a certain period of time, a certain amount of anti-fogging liquid is attached to the surface of the substrate, and then processed at a certain temperature to form a uniform nano-anti-fogging coating.

Characteristics:

Application Scenarios:

Widely used in daily consumer products such as swimming goggles, ski goggles, protective goggles, and bathroom mirrors; electronic equipment that requires a clear field of vision, such as security cameras and lidar covers; parts of automobiles such as windshields, side windows, and rearview mirrors; and building materials such as building windows and curtain walls to ensure a clear field of vision in extreme environments.
