There are two main types of silicone adhesives: rubber type and resin type. Silicone adhesives have the characteristics of high temperature resistance, stable adhesion, and good durability. They are widely used in various fields such as aviation, navigation, spacecraft, rocket missiles, atomic energy, and electronic and electrical industries.
       As the application scope of silicone adhesive tapes gradually expands, various industries have put forward new requirements for the quality and properties of silicone adhesive tapes. Many irregular and differently processed bonding surfaces have transformed the application of silicone adhesive tapes from simple to special uses. The general preparation process of silicone adhesive tape is to coat the silicone adhesive on the surface of the tape base material (such as various films, paper, etc.). One of the major uses of silicone adhesive tape is to make a protective film, which is used to protect the surface of glass, metal sheets, plastic sheets and other materials during transportation or use, so that the surface is free from contact contamination or wear marks and scratches.
       When the silicone adhesive tape protective film protects the surface of electronic products, these surfaces will be coated with some chemical substances such as water-based paints and varnishes. In general processes, these surfaces have residues of chemical solvents, small molecules, etc., so using existing A silicone adhesive protective film is attached to the surface to protect it. When used, because the silicone adhesive layer is flat and tight, there is no exhaust channel between the protected surface and the silicone adhesive. The residual small molecular substances cannot be discharged when they volatilize. When used for a long time, color difference, ring marks, odor and other undesirable effects will occur. This phenomenon is caused by the fact that silicone is super flat and cannot breathe.
