Fluorine free anti fingerprint oil, also known as anti fingerprint coating, fluorine free coating/anti fingerprint coating, anti glare coating

AG coating is applied to reduce light reflection, allowing the screen to be clearly visible even in bright places.

Anti fingerprint glass+screen protector

How important it is to purchase a product that can prevent fingerprints, keep the screen protector clear and clean, and protect the screen from scratches. Today, the editor will introduce AF anti fingerprint oil solution, which is not only used on glass covers, AF glass, and mobile phone screens, but also widely used in touch sensor panels and controllers. For example, resistive touch screens are used in various devices such as bank ATMs, train station ticket machines, and especially as reliable touch screens in industrial applications.

The anti fingerprint coating of the seismometer AF can prevent fingerprints and other oils and dust from adhering to the screen. The fingerprint traces on the screen are not obvious, and the elongation caused by oil and grease can be easily removed when wiping. It is easy to clean, keeps the screen clean, and prevents fingerprints from sticking to the screen even during frequent touch operations.

Firstly, fluorine free anti fingerprint oil is mainly composed of fluorinated polymers (such as PFPE, fluorosiloxane) or siloxane materials, which are attached to the surface of the substrate through coating processes (spraying, coating, soaking, etc.).

Secondly, AF oil should be made of non-conductive material with uniform thickness to avoid interfering with the electric field induction of capacitive touch.

Thickness: Usually at the nanometer level (5-50nm), it hardly affects the optical performance or touch accuracy of the sensor. Generally, the surface of the product treated with AF anti fingerprint oil has the following characteristics:

1. AF anti fingerprint oil reduces surface tension, making it difficult for fingerprint oil to adhere or form a uniform thin layer, thereby reducing visual pollution.

2. Anti fingerprint oil solution enhances surface smoothness: improves surface smoothness and optimizes the tactile experience of touch operations (such as the "silky" experience of mobile phone screens).

3. Anti fingerprint medicine can play a role in anti fouling and easy cleaning, reducing dust, water stains, and facilitating daily maintenance.

4. AF anti fingerprint oil balances hydrophobic and oleophobic properties: a low surface energy may cause an "air film effect" between the finger and the screen, affecting touch accuracy. Therefore, process optimization (such as controlling coating roughness) is needed to balance anti fingerprint and touch performance.

Finally, anti fingerprint medication can have the characteristic of scratch resistance: the hardness needs to be ≥ 2H (pencil hardness test), to avoid coating wear caused by frequent touch (such as the car center control screen needs to pass 5000 friction tests).

In summary, anti fingerprint film has oil resistant and oil repellent coatings, which can prevent fingerprints and other oil stains from depositing on mobile phones and glass screens, making them relatively easy to wipe. AF anti fingerprint oil solution also helps to improve visibility and operability by wiping oil stains that are easily extended during the wiping process.
