Anti fingerprint oil (AF oil) is a functional coating material used in the fields of glass, electronic manufacturing, and other surfaces. Its main function is to form an ultra-thin transparent protective film on the surface of objects, which can reduce the attachment of fingerprints and oil stains, and improve the surface's scratch resistance, hydrophobicity, and oleophobicity, while maintaining the original texture and aesthetics of the substrate.

AF anti fingerprint oil has many unique properties as an oil repellent optical anti reflective coating in the series of oil repellent and ordinary anti reflective coatings. In addition, there is a durable and oil resistant oil repellent coating on the side of the operator, which has the functions of preventing fingerprints, removing liquids and dirt.

Traditional reflective coatings display glass by minimizing surface reflection and maximizing display contrast. However, once the user touches the non reflective screen, the fingerprint will leave visible traces on the reflective coating. 

This interference with image reproduction and aesthetics is a well-known problem, especially in touch displays in public spaces. The series of anti fingerprint oils developed by Zhenyi Co., Ltd. provide the best solution for such applications. The oil repellent coating reduces the visibility of user side fingerprints by 90%, and the adhesion of dirt and liquid is much lower than that of traditional anti reflective coated glass.

The hydrophobic and oleophobic AF anti fingerprint oil coating is very durable, and in the steel wool wear resistance test, it can resist hundreds of thousands of friction cycles. So, using soft and dry fabric is easy to clean. AF anti fingerprint oil solution in the glass field can improve light transmittance and ensure excellent imaging quality.

What is anti fingerprint coating technology?

Anti fingerprint (AFP) smartphone coating can prevent fingerprints from remaining on the surface, the ability to hide fingerprints, and oil stains that hide fingerprints. In environments where humans frequently come into contact (such as smartphones or other personal electronic devices) or in environments with high concentrations of oily residues and dirt deposits, patented anti fingerprint surface coatings and treatment methods have been successful. Most of these surfaces quickly become very dirty, displaying fingerprints and stains. 

AF anti fingerprint oil can significantly reduce and eliminate stains and fingerprint visibility, while significantly improving cleaning convenience.

The anti fingerprint coating adheres a nanometer thick fingerprint hiding layer on various substrates, endowing fingerprints with hidden and easy to clean characteristics. In addition, it also reduces residual fingerprints and stains on mobile phone screens

Fingerprints are everywhere, and consumers will leave unsightly fingerprints anywhere they come into contact with the product. Therefore, the appearance and quality of all products will be compromised, and the optical quality of touch screens will significantly decrease. Fingerprints are an urgent issue in many markets that use touch screens or portable devices. By reducing the appearance of surface fingerprints, the AF anti fingerprint coating technology of Zhenyi Corporation will greatly improve the consumer experience.

The process flow and key points of anti fingerprint oil are usually as follows:

1. Substrate pretreatment:

For example, electronic products, glass cover plates and other substrates need to be cleaned with an argon oxygen plasma cleaning machine before processing to remove surface residues such as grease and dust, ensuring the adhesion of subsequent AF oil spraying.

2. After plasma cleaning, apply AF oil and use AF spraying method to evenly spray with atomizing nozzle, suitable for complex curved surfaces (such as irregular glass cover plates), with a coating thickness controlled at 50-200 nm.

Anti fingerprint oil solution, through the low surface energy characteristics of fluorosilicon chemistry and the strengthening effect of nanomaterials, not only maintains the original

 characteristics of the substrate, but also endows it with multiple functions such as anti fingerprint, easy cleaning, and wear resistance. It has become a key technology for improving product quality and practicality in fields such as 3C consumer electronics and automobiles. I believe that in the near future, AF oil will develop towards water-based and solvent-free directions,

 and can also expand more application possibilities in various emerging scenarios. If you need to know about nano anti fingerprint oil, glass anti fingerprint oil, quick drying anti fingerprint oil liquid, etc., you can contact our vibration tester partners for in-depth communication!
