1. With proper surface tension, the adhesive or another substrate can be well matted on its surface.

2. Has certain polarity or contains some memory functional groups, so that the substrate has a good adsorption to adhesives or another substrate.

3. The substrate contains certain functional groups that enable it to form strong bonds with an adhesive or another substrate.

4. The micro surface of the substrate has a certain roughness and porosity, allowing the adhesive or another substrate to infiltrate into the gap and form a strong mechanical bond.

5. For the plastic substrate, the polymer chain should have good flexibility so that the polymer chain or chain segment has good diffusion capacity under the action of higher temperature.
