3M Marine Adhesive Sealant 5200 is a one-component, high-strength, moisture-curing, gap-filling polyurethane sealant designed for permanent bonding in marine environments.

This trusted sealant has been relied upon throughout the marine industry for over 50 years. It works above and below the waterline, providing durable protection against harsh saltwater conditions, weathering, and the natural flex and movement of a boat's hull. Whether you're a professional or a DIY enthusiast tackling boat repairs, this adhesive-sealant delivers the strength and reliability needed to keep your vessel watertight and secure.

Features and Benefits
