You can use AB glue or 3M glue to attach the tempered film. AB glue is a two-component epoxy glue with strong adhesion and weather resistance, suitable for long-term sticking. 3M adhesive is a strong adhesive tape that provides reliable bonding. Choosing AB glue or 3M glue can be decided according to the specific use environment and personal preferences. Whichever glue you choose, make sure the surface is clean and the instructions for use are followed correctly.
