Test method for pet protective film adhesive system

At present, there are three types of adhesives in the pet protective film industry: silicone, acrylic, and PU. So, what is the test method of PET protective film adhesive system? 1. Smell with your nose: Silicone protective film and PU protective film smell nothing, acrylic protective film and PU protective film will have a little smell, as long as you open the release film and smell it, it is easy to distinguish; 2. Scrape the rubber surface with nails, silicone The protective film and PU protective film are not easy to show traces, and the acrylic protective film can be easily hung with a fingernail. It is a silicone protective film, and if it is in the shape of water droplets, it is an acrylic adhesive protective film or a PU adhesive protective film. The principle is very simple. Generally, the silicone protective film will directly use the original film as the release film, while the acrylic protective film and PU protective film need to be coated with a layer of silicone oil on the release film; 4. Touch the release film by hand: the release film of the silicone protective film. The film will be astringent, the PU protective film and acrylic protective film will be more slippery, the principle is the same as above; 5. Look at the exhaust: directly cut a small piece of protective film and stick it on the glass, the exhaust of silicone is the best, and the PU glue is slightly Almost, acrylic has very poor exhaust. 6. Burning: Hang the glue on the PET surface with a knife and burn it with a lighter. The ash of the silicone is white, and the PU and acrylic will melt first.
