This invention relates to the field of tape technology, specifically to an ultra-thin green PET pressure-sensitive
adhesive tape with a high gyrometric
coating reinforcement. The tape comprises a green
PET substrate with a thickness ≤12μm and a primer reinforcement layer and a pressure-sensitive
adhesive layer sequentially arranged therefrom. The primer reinforcement layer consists of an anchoring primer layer, an intermediate primer layer, a borate ester dynamic covalent pre-organized layer, an iron-
citric acid slow-release
coordination layer, a free trivalent iron locking layer, and a pH
recovery and shaping layer. Through multi-layer synergistic action, it maintains
high surface energy for a long time, significantly improving the
interfacial bonding strength with water-based pressure-sensitive adhesives, resistance to
damp heat aging, and resistance to die-
cutting edge warping, while maintaining the flexibility of the substrate, making it suitable for the field of precision electronic
assembly.
