The excellent quality of the tempered glass film can reduce the fingerprint’s residue on the glass film ,but it could not completely eliminate the fingerprints. The method is to add a layer of anti-fingerprint oil on the surface of the tempered glass film, And this layer of anti-fingerprint oil coating can also ensure that the stains cover the surface of the tempered glass film can be easily removed.

High-end point is the hand coated with fingerprint oil, the so-called hand painted is hand a brush, and means that the anti-fingerprint oil directly is applied to the surface of the glass film by artificial, but the disadvantage of anti-fingerprint effect is not uniform and is easy to fade against fingerprint oil.

 More high-end process is machine coating or plasma spray fingerprint oil, and generally a small size and a little conscience of the manufacturers are selected with this. This process is better than the hand painted in some way, but the disadvantage is poor persistence . The actual situation ,it is to use about 20 days, you will find the anti-fingerprint effect has been greatly reduced, because the anti-fingerprint oil have been polished. 

In the market, the top of the anti-fingerprint oil is plating anti-fingerprint oil, In general, only a few manufacturers of high-end tempered glass film using plating anti-fingerprint oil. For the principle of electroplating here ,I am not ready to take much time to explain, In short, after plating anti-fingerprint oil technology tempered glass film effect is reflected in the more smooth, The effect is more lasting long term ,and generally it can last about 2 months or more.
