… Not enough info here. Need to know more about your application.
1. Is it a high strain interface? If so you’ll be best to use an elastomer based adhesive.
2. What does your bond line look like? Do you have a well-prepared surface, as in etched, scuffed and clean? Do a water break test after prep.
3. Best to go with an elevated temperature cure film adhesive. Make certain it has scrim cloth, mesh or other bond line thickness management medium in it.
4. If surfaces aren’t matched well best to stick with a paste adhesive. Use an “over the counter” two-part epoxy. Again, use micro-spheres as a bond line thickness controller.
5. Service envelope. Will your system be exposed to elevated temperatures? High humidity? Salt or UV rays?
… Or are you just fixing the kids tricycle?
