3M 5200 Marine Adhesive Sealant is a high-strength, one-part polyurethane designed for permanent bonding in demanding maritime environments. This moisture-curing sealant creates a tough, flexible, and watertight seal on substrates including wood, gelcoat, and fiberglass, performing reliably both above and below the waterline. Its superior elasticity allows it to effectively dissipate stress caused by vibration, shock, and thermal expansion. Ideal for structural applications such as hull-to-deck joints, through-hull fittings, and deck hardware, it remains non-shrinking and highly resistant to saltwater and weathering. The 3 oz tube format is optimized for precision application and small-scale repairs requiring an industry-standard permanent bond.
