5200 FC (Fast Cure) is a faster curing version of 3M's popular 5200 marine sealant. With nearly the same tensile strength as original 5200 and significantly faster cure time, Fast Cure is designed for use where permanent bonds are needed quickly.
Easy to apply with a standard caulking gun, this high performance polyurethane adhesive becomes tack free in one hour and fully cures in approximately 24 hours. The seal is extremely strong, retaining its strength above or below the water line. 5200 FC stays flexible and allows for structural movement. It has excellent resistance to weathering.
