With the development of the times, many people choose ordinary and affordable mobile phone protective films. However, this type of protective film does not have a hydrophobic or oil repellent layer on it, and it will be more convergent and rough when sliding in contact. Long term use of mobile phones can result in a lot of fingerprint stains on the protective film, which are difficult to wipe and further increase sliding resistance. Without fingerprint oil, there will be a noticeable sense of sliding resistance, making it easy to leave fingerprint stains and difficult to wipe.

Fluorine free anti fingerprint oil, I believe everyone is familiar with this term, and at the same time, I believe some people may be confused about it. 

What is fingerprint oil? What is its function? Actually, fingerprint oil layer is very common in daily life, but when you touch it, you don't notice it.

Fluorine free anti fingerprint oil can effectively reduce the friction coefficient of the surface by forming a uniform protective film on the surface of the object, making it difficult for fingers to leave obvious fingerprint marks after contact. Moreover, it can make it difficult for fingerprints to adhere to the surface. Even if a small amount of fingerprints are left, they will be more easily wiped off due to the special properties of the surface, maintaining the cleanliness and beauty of the object surface. Compared with traditional fluorine-containing anti fingerprint oil, fluorine elements may cause certain harm to the environment. For example, fluorine-containing compounds are difficult to degrade in the natural environment, and may accumulate and have potential impacts on the ecosystem. 

And fluorine free anti fingerprint oil does not contain fluorine elements, which meets environmental protection requirements. It has less pollution to the environment during production, use, and waste disposal, and is more in line with the current trend of green environmental protection. Today, let's learn and explore the principles, application cases, and how to choose a suitable anti fingerprint oil?

AF material is usually a fluoride coating with low surface tension, whose main function is to adhere to the surface of the wire mesh, achieving the effect of increasing the hydrophobicity, oleophobicity, and anti fouling of the wire mesh surface. Currently, it is widely used in protective glass such as mobile phones, tablets, displays, DSLR cameras, etc.

In real life, we can almost touch electronic products on the screen at any time, and this hydrophobic and oil repellent effect is like water droplets on lotus leaves.

After the glass coating is coated with anti fingerprint oil, the AF coating will still remain on the screen surface after high-temperature curing. In addition to anti fouling, the AF coating also has the characteristics of wear resistance and high transmittance. If the concentration of AF coating is slightly higher, there will be no problem within 1-2 years after vacuum evaporation. The charm of anti fingerprint oil in terms of hydrophobicity, oil drainage, and anti fouling cannot be underestimated,

How to choose the appropriate anti fingerprint oil?

Anti fingerprint oi, abbreviated as AF, is a colorless and odorless transparent liquid. Directly spray or dilute to a certain concentration, and evenly spray on substrates such as glass cover plates, mobile phone tempered films, glass screens, etc. After natural drying or heating drying, a nanoscale coating is formed on the surface, achieving waterproof, oil resistant, stain resistant, fingerprint resistant, smooth and wear-resistant effects without affecting the visual effect.

The main materials for anti fingerprint oil are fluorinated long-chain alkyl silane coupling agents and fluorinated diluents. However, the current anti fingerprint oil has the disadvantages of insufficient waterproof, oil resistant, and anti fouling performance, and is not smooth. Anti fingerprint oil is a special functional coating material widely used in many fields. The following are its main applications:

1. In the field of electronic products, such as mobile phones/tablets, anti fingerprint oil is commonly used on the screens, shells, and buttons of mobile phones and tablets to effectively prevent fingerprints from being left by finger touch, maintain the appearance of the product neat and beautiful, and enhance the visual experience and product texture of users. 

At the same time, anti fingerprint oil also has certain wear resistance and scratch resistance, which can protect the screen and shell from scratches and wear during daily use.

2. In the field of automotive interior, anti fingerprint oil is used for displays and various control buttons on car dashboards, which can prevent fingerprints of drivers and passengers from being left on them, keep the dashboard clean and tidy, allow drivers to read information more clearly, and improve driving safety and interior aesthetics.

3. Automotive interior parts: Anti fingerprint oil is also used for internal components such as car door handles, center console, seat adjustment buttons, etc. These parts are often touched, which can easily leave fingerprints and stains. Anti fingerprint oil can make them easier to clean and maintain the high-end feel of the interior.

4. In the field of glass products, anti fingerprint oil is used for furniture such as glass coffee tables and glass display cabinets. It can prevent the surface of furniture from being stained with fingerprints and stains, maintain its crystal clear appearance, and improve the quality and grade of furniture.
