3M Marine Adhesive Sealant 4200 Fast Cure White 10 oz

A one-part, general all-purpose polyurethane that chemically reacts with moisture to deliver flexible bonds with good adhesion to wood, fiberglass, Gelcoat, plastics, and metals.

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.

On plastics, test 3M™ Marine Adhesive/Sealant Fast Cure 4200 to determine suitability. 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.
