Pressure-sensitive tape is a special type of tape, which is made by applying a special adhesive, namely pressure-sensitive adhesive, on a tape substrate. Pressure-sensitive adhesive is the most important component of pressure-sensitive tape. The function of pressure-sensitive adhesive is to make the tape have pressure-sensitive adhesion properties. Pressure-sensitive tape can achieve the bonding effect by applying pressure for a short time. Pressure-sensitive tape overcomes the solvent volatilization and the required drying time during the operation of structural adhesive, and can improve the working environment. After peeling off, pressure-sensitive tape will not contaminate the adherend, can be corrected when pasted incorrectly, and can be reused many times. Pressure-sensitive tape has stable performance, is not easy to change color, and has good adhesion to the substrate.
