Adhesive Sealant 10 Oz

3M Marine Adhesive Sealant Fast Cure 4200FC is a one-component, moisture-curing polyurethane sealant engineered for demanding marine applications. This gap-filling sealant creates strong, flexible bonds to wood, fiberglass, gelcoat, aluminum and metals, forming water-tight, weather-resistant seals both above and below the waterline. Whether you're sealing rub rails, access plates, joints, seams or boat hardware, this fast-cure formula delivers reliable protection against water intrusion and the harsh marine environment.

The flexibility of this polyurethane sealant allows it to absorb stress caused by shock, vibration, swelling and shrinking—critical for vessels that experience constant movement and temperature changes. Once cured, it remains permanently elastic, enabling disassembly of sealed parts when needed. The one-component design means you apply it directly from the tube without mixing or adding a second component, saving time on the job.
