Feature 1: Good adhesion, good conformability, solvent resistance, used in normal temperature environment, straight edge, no glue residue. Use: Suitable for decoration and general industrial shelter. Feature 2: Good adhesion performance, good solvent resistance, good weather resistance, suitable for use at a temperature of about 150°C, no glue residue, and clear separation lines. Use: Suitable for color separation and masking of automobiles, and spray painting of industrial machines. Feature 3: Good high temperature resistance, good viscosity, high tensile strength, acid and alkali resistance, impermeability, no glue residue. Use: It is suitable for spraying and baking paint type electrostatic screen protective film in high temperature environment. The self-adhesive protective film has the advantages of low cost, no residual glue, uniform viscosity and easy control. For some applications with higher requirements, there are economic and technical advantages; therefore, the use of self-adhesive protective film is the general trend, and the market share has also been increasing.
