AI Technical Summary
Existing paint protection film is prone to air bubbles during the application process, has insufficient adhesion, and tends to peel off after long-term use, resulting in low construction efficiency.
It adopts a combination structure of release film layer, pressure-sensitive adhesive layer, PET substrate layer and UV protection layer. The pressure-sensitive adhesive layer has adhesive protrusions at the bottom and limiting grooves at the top. The PET substrate layer has limiting protrusions at the bottom. Combined with thermosetting polyurethane coating and anti-UV coating, it forms venting gap and limiting fit to improve the adhesion.
It effectively removes air bubbles, improves bonding strength, prevents edge curling and detachment, enhances construction efficiency, and has resistance to ultraviolet rays and chemical corrosion.
