There are two forms of liquid phone protectors: one is the plastic film, and the other is the tempered glass screen protector.
First, I will explain how it works. Usually the plastic film is made of a layer of PET original film + a layer of coated silica gel + a layer of PET release liner, so there are three layers. The tempered glass screen protector is made of a layer of glass + a layer of acrylic glue + a layer of PET original film + a layer of coated silica gel + a layer of PET release liner, a total of five layers.
1. Plastic film
The first layer of the plastic film is made of the PET original film, which is usually the one pasted on the screen of the new mobile phone; the second layer is coated with silica gel in the 10,000-class dust-free workshop, so its peeling force is relatively low, and the content of silicone oil which separates out is low, making the light transmittance higher than 90%; the third layer is a PET release liner, which is mainly used to coat the PET original film attached to the silica gel. And bake it to dry, and attach it to the other side of the protective coated silica gel layer to avoid the pollution caused by dust and oil.
2. Tempered glass screen protector
The tempered glass screen protector is more complicated, with a total of 5 layers. Its processing technique is different from that of the PET liquid phone protector. The tempered glass screen protector is mainly made of glass film pasted with AB glue. The first layer is tempered glass, the second layer is acrylic glue, which is mainly attached with glass and PET original film, and the third layer is PET original film, which is used to carry acrylic glue and coated silica gel. The fourth layer is the coated silica gel which is affixed to the PET original film, and the fifth layer is a PET release liner, which is mainly used to protect the cross-section of the tempered glass.
