3M: Marine Adhesive/Sealant Fast Cure 5200

This high-performance polyurethane becomes tack free in one hour and fully cures in approximately 24 hours.

The seal is extremely strong, retains its strength above or below the water line. Stays flexible too - allows for structural movement. Has excellent resistance to weathering and salt water.

Stress caused by shock, vibration, swelling or shrinking is effectively absorbed. This is a faster curing version of 3M Marine Adhesive/Sealant 5200.
