The transparency characteristics of glass protective film

- Aug 25, 2020-

In the process of using the glass protective film, the types of adhesives for the coating film include solvent-based rubber adhesives, solvent-based acrylic adhesives, water-based acrylic adhesives, and silicone adhesives. Among them, water-based acrylic adhesives are commonly used in such products, which can easily adjust the adhesion, and have good transparency and weather resistance.

Glass protective film is generally produced by co-extrusion, and its self-adhesive layer is generally EVA, ultra-low density polyethylene or polyolefin plastomer resin. This structure has gradually become the mainstream of the market because it is more coated Adhesive film has many advantages, such as no residual glue, providing stable adhesion, reducing user costs and creating higher profits for protective film manufacturers.

The glass protective film should first be viewed when the monitor is turned off. The method is the same as above. After the various protective films are pasted one by one, the less the haze of the background color of the screen is, the smaller the haze, the better the material. This method It is easier to see the difference if you use a black test board.

Another way to protect the film is to turn on a fluorescent lamp in a slightly darkened room, tear off the protective film from the top and bottom of the release film, and hold it with your hand between the eyes and the light. Look carefully to see if there is a layer of fog. Evenly distributed in the protective film, that is the culprit that affects the haze. The more severe the haze, the greater the haze and the worse the material, and vice versa.
