3M 4200 Fast Cure Polyurethane Marine Adhesive Sealant, White, 10 oz Cartridge
3M 4200 Fast Cure Polyurethane Marine Adhesive Sealant, White, 10 oz Cartridge
3M 4200 Fast Cure is a one-component, medium-strength, moisture-curing polyurethane adhesive-sealant built for marine bonding and sealing jobs both above and below the waterline. It is a gap-filling formula that delivers strong, flexible bonds to aluminum, wood, gelcoat, and fiberglass, and it stays flexible after curing so it can absorb the stress of shock, vibration, and hull swelling or shrinking without cracking or losing its seal. Because it is a medium-strength bond, parts sealed with 3M 4200 can still be disassembled later without the damage a permanent adhesive would cause.
This is the fast-cure version of the 3M 4200 line: it becomes tack-free in about 1 hour and typically reaches a full cure in 24 hours, so projects move along faster than with standard-cure sealants. It comes in a 10 fluid ounce (295 milliliter) cartridge sized for a standard caulking gun, in white.
Recommended applications include fiberglass deck-to-hull joints, wood-to-fiberglass bonding, portholes, deck fittings, rubrail attachment, sealing screw holes, and stanchion supports. It forms a watertight, weather-resistant seal that is designed to hold up in marine environments where materials contract and expand and hardware is exposed to constant vibration and water exposure.
