3M MARINE ADHESIVE/SEALANT FAST CURE 4200
Bonds and seals fiberglass, gelcoat and wood. Ideal for rub-rails, stern-joints, deck and through-hull fittings, and access plates. Medium strength allows for disassembly.
A one-part general purpose polyurethane that chemically reacts with moisture to deliver flexible bonds with good adhesion to wood, fiberglass, gelcoat, certain plastics and metals. Sandable. Forms watertight, weather-resistant seals on joints and boat hardware above or below the waterline. This product is approximately half the strength of 3M™ Marine Adhesive/Sealant 5200, which allows for disassembly of parts. Note: When very high strength or unremovable bonds are required, use 3M™ Marine Adhesive/Sealant 5200 or 3M™ Marine Adhesive/Sealant Fast Cure 5200. Not recommended for sealing wood decks because it may be permanently softened by certain teak cleaners or sealers. On plastics, test 3M™ Marine Adhesive/Sealant Fast Cure 4200 to determine suitability.
