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 suitable for marine applications both above and below the waterline. This sealant features high-performance bonding that allows for disassembly, excellent UV resistance, color stability, and a skin time of 15-20 minutes to help maintain workflow efficiency. Additionally, it is paintable immediately after application and can be removed if rework or repair is necessary. Recommended applications include electrical assembly, hatch installation, stanchion supports, thru-hull fittings and deck hardware, porthole frames, and sealing screw holes. The product complies with industry standards and is designed for reliable long-term performance in marine environments.
