A fast curing, one-part polyurethane that chemically reacts with moisture to deliver strong, flexible bonds to wood, gelcoat and fiberglass. It forms watertight, weather-resistant seals on joints and boat hardware above and below the waterline. In addition, its flexibility allows for dissipation of stress caused by shock, vibration, swelling or shrinking.
3M™ Adhesive Sealant Fast Cure 4200 is designed to allow disassembly of wood and fiberglass parts bonded together. If a permanent bond is desired, use 3M™ Marine Adhesive Sealant 5200 or Marine Adhesive Sealant Fast Cure 5200.
