PVC to Aluminum

[NorthCoastJoe]

What is a good adhesive to bond PVC to aluminum ? I have a aluminum hatch frame with a pvc panel. I tried 3M 4300, if failed, stuck to the aluminum very well but not the pvc. Anyone have with experience with this problem?

Have you tried Sikaflex 291?

"Sikaflex® 291
Sikaflex-291 is a non-sag 1-c polyurethane sealant specifically developed for the marine market, which cures on exposure to atmospheric moisture form a durable elastomer.

It is suitable for making elastic, vibration-resistant joint seals, and can also be used for a variety of interior and exterior sealing applications. Sikaflex-291 bonds extremely well to the materials commonly used in marine construction like wood, metals, metal primers and paint coatings (2-c systems), ceramic materials and plastics (GRP, etc.)"
