3M 5200 Marine Adhesive Sealant: Superior Waterline Bonding Solution for Boats
3M 5200 is a single-component, moisture-curing polyurethane adhesive sealant designed for permanent bonding in marine environments. It offers high strength, flexibility, and resistance to saltwater, UV, and vibrations. Available in fast-cure (5200 FC) and slow-cure variants, it cures to form a waterproof seal that withstands submersion above and below the waterline. Standard packaging includes 295 mL tubes (12 tubes/box) or 88.7 mL sausages, with a shelf life of 24 months
3M 5200 is engineered for demanding marine applications, providing a durable and flexible bond between materials like wood, gel coat, fiberglass, and metals. Its unique polyurethane formulation reacts with moisture to create a resilient seal that absorbs stress from expansion, contraction, and impact. Ideal for both manufacturing and repair, it ensures long-term performance in harsh oceanic conditions
