The 3M Marine Adhesive Sealant 5200 is a single-component, high-strength, moisture-curing, gap-filling polyurethane for permanent bonding of wood, gelcoat and fiberglass. It cures to form a firm, rubbery, waterproof seal on joints and boat hardware, both above and below the waterline. In addition, our marine adhesive sealant is flexible and allows for structural movement and dissipation of stress that may be caused by vibration, swelling, shrinking or shock. Available in both cartridge and sausage packs to meet your application requirements.
