1. According to the paint material, aluminum-plastic panels can be divided into two categories: polyester aluminum-plastic panels and fluorocarbon aluminum-plastic panels, each of which can be roughly divided into metallic paint and non-golden paint. Due to the difference in paint surface material and structure, different requirements are put forward on the thickness and viscosity of the protective film glue.
2. In the process of use, if the glue properties of the protective film are not properly selected or the glue quality is unstable, it will cause many problems to the user, such as not sticking, curling, or not tearing off within the shelf life after being stuck. .
3. The viscosity of the surface protective film should be selected according to the smoothness of the material surface. The surface of the material is smooth and smooth. The viscosity of the protective film should be low, the surface of the material should be rough, and the particles of the coating surface should be relatively coarse. The viscosity of the protective film should be high. On the contrary, if you choose to use it improperly, it will cause the phenomenon that the sticking is not firm or the sticking is too firm and cannot be removed.
4. For a given surface, it is extremely important to select the appropriate glue and viscosity, and the subsequent processing steps are the key to determining the viscosity. Subsequent processing generally includes bending and stamping. Generally, a low-viscosity protective film is used for smooth surfaces, with a viscosity of 0.9N/cm; a medium-viscosity protective film is used for medium-rough surfaces, with a viscosity of 1.2N/cm.https://www.pe-protectionfilm.com/
