Hello! I want to make watertight transparent removable canopy on boats. We need adhesive to glue Makrolon https://solutions.covestro.com/en/brands/makrolon. with waterproof Zipper like this https://www.aliexpress.com/i/32885604704.html. Do you have any solutions to my problem? Glue must be very heavy duty.
That looks like an interesting application. A good place to start with this would be a structural acrylic as they will be more resistant to plasticizer migration from the PVC zipper. 3M™ Scotch-Weld™ Acrylic Adhesive DP8410NS Green is a structural acrylic you should try as it has excellent overlap shear strength to both PVC and high surface energy plastics.
