3M™ Marine Adhesive Sealant Fast Cure 4200FC is a multi-purpose adhesive sealant made specifically for the marine market. This medium-strength adhesive forms a weather-resistant seal that still allows for disassembly. It's unique formula reacts with moisture to cure fast, forming a tack-free skin in 1 hour and fully curing in 24. Ideal for use above and below the waterline, it reliably bonds dissimilar materials including wood, fiberglass, gelcoat, plastics, and metals. Polyurethane sealants such as this form permanently flexible, elastomeric bonds that seal against the elements, maintain joint movement, and absorb stress caused by shock, vibration, swelling or shrinking. Such durability, versatility, and flexibility prepare 3M™ Marine Adhesive Sealant Fast Cure 4200FC for tough applications like sealing portholes, deck/hull fittings, rub rail attachment, screw holes, and stanchion supports.
3M Marine Adhesive Sealant Fast Cure 4200 is a tough, semi-permanent, flexible polyurethane for bonding and sealing. It is ideal for use on wood, glass, paint, gelcoat and fiberglass as well as many metals and plastics. It becomes tack-free in as little as 50 to 90 minutes, and typically cures in as little as 24 hours – allowing you to get back out on the water. The sealant applies right from the container with no metering or mixing required and cures to form a firm, flexible, waterproof seal, yet this medium-strength adhesive allows you to disassemble parts after long-term use without damage. It is recommended for use on joints, hardware attachment, portholes and other areas which are shielded from the sun. Tough and flexible, it dissipates stress caused by vibration and shock, and won’t crack under dynamic force. It resists saltwater, wind, weather and temperature extremes for long periods of worry-free enjoyment on the water.
