Products：

Anti-fingerprint coating granule is a coating product for PVD equipment.

The anti-fingerprint coating particles evaporate the AF components adsorbed in the carrier to the surface of glass or film under vacuum heat to form a hydrophobic and oleophobic nano-scale film layer, which can effectively reduce the adhesion of fingerprints and all kinds of stains, and at the same time improve the product surface resistance to abrasion, UV, salt spray, chemicals, high temperature and high humidity.

Anti-fingerprint coating particles are mainly used in mobile phones and computer screens, automotive glass, eyeglasses, camera lenses and so on.

Dongxing S/H series anti-fingerprint coating particles is a vacuum thermal evaporation coating product. Different models are customised according to the performance requirements of different customers and the conditions of different vacuum coating machines (chamber size, evaporation method, heating carrier style).

Application scenario：

（Ⅰ）Wear-resistant AF stock solution

Products：

AF Original Fluid is a colourless, odourless and transparent liquid composed of fluorosilicone polymer, which is suitable for antifouling and anti-fingerprint treatment on the surface of high alumina silicon glass, mobile phone glass cover, glass protection sticker, electronic display, optical lens and metal substrate. After treatment, the surface of the substrate forms a complete protective film that is waterproof, anti-fouling and anti-fingerprint, with superior adhesion, very low surface tension, excellent hydrophobicity and oleophobicity, anti-fingerprint, easy to wipe, and high smoothness.

AF Fingerprint Resistant Features

Suitable for a wide range of substrates, with hydrophobic and oleophobic properties, anti-fingerprint adhesion. At the same time, it has the properties of smoothness, salt spray resistance, chemical resistance, high temperature and high humidity resistance, and UV resistance.

- For the film substrate, a unique formula is used to make the anti-fingerprint coating more excellent abrasion and rub resistance, such as wool felt CS-3, CS-5.
- AR + AF process of coating, using a special formula, with excellent adhesion, can withstand steel wool more than 3000 times, eraser 3000 times, in the salt spray and lye and other ring measurement data can also do very good results.
- Anti-fingerprint coating on the surface of metal substrates developed high-performance formulations, excellent performance in salt spray resistance, lye resistance, etc., and successfully developed stainless steel, anodising, electroplating and other areas of coating processing.
- The UV-resistant AF products developed have excellent UV-resistant performance to meet the needs of outdoor use, and can be widely used in the automotive field, photovoltaic field, and outdoor construction field.

Dongxing DX Series Anti-fingerprint Main Agent

- High-end series DXS, the current steel wool can do 30,000 times, eraser can do 8,000 times.
- Mid-range series DXZ, to meet the needs of most customers, the performance of Japan's Daikin, Shin-Etsu and other companies competing products.
- Ultra-low-end field, no-bake anti-fingerprint liquid MK series, construction is extremely simple, in outdoor construction, curtain walls and other areas can be developed and used in bulk.
- Customisable series, Tohko's own derivatives, special products in the field of anti-bacteria, anti-UV, anti-handsweat, etc., can be accepted for development and customisation.
