Product Details
3M™ Marine Adhesive Sealant 4000 UV is a one-component, medium-strength, moisture-curing, gap-filling sealant that cures to form a firm, flexible, and waterproof seal on aluminum, wood, gel coat, and fiberglass, making it well-suited for marine applications both above and below the waterline. This product features multi-purpose bonding with long-lasting seals, and it remains permanently elastic to allow for joint movement. With a skin time of 60-90 minutes, it is paintable once the skin forms. The sealant offers good UV resistance, simplifies production with its one-component formula, and bonds dissimilar materials for increased design flexibility while providing gap-filling capability. Recommended applications include electrical assembly hatches, stanchion supports, thru-hull fittings and deck hardware, porthole frames, and sealing screw holes.
