Marine Adhesive Sealant

3M™ Marine Adhesive Sealant 5200 is a high-strength, single-component polyurethane that cures with moisture and fills gaps for permanent bonding of wood, gel coat, and fiberglass. It cures to form a tough, rubbery, and waterproof seal on boat joints and structures, both above and below the waterline. This product has been trusted across the marine industry for over 50 years.

Durable and Flexible for Strong Bonds

Creating watertight seals, the 3M™ Marine Adhesive Sealant 5200 provides permanent adhesion to wood, gel coat, and fiberglass. Additionally, our marine adhesive sealant is flexible, accommodating structural movement and dissipating stress caused by vibration, expansion, contraction, or impact. Available in cartridge and sausage formats to meet various application needs.

Combats Vibration, Expansion, Contraction, and Impact

The 3M™ Marine Adhesive Sealant 5200 is designed to meet the demanding requirements of the marine environment, making it ideal for creating bonds resistant to saltwater and harsh weather. We formulated our sealant to provide an exceptionally strong solution for marine conditions while offering the flexibility needed to withstand vibrations, expansion, contraction, and impacts. Once again, despite the challenges of a rugged marine environment, 3M relied on science to deliver a reliable, long-lasting solution.

Understanding Polyurethane Sealants

Polyurethane sealants provide strong, flexible, and durable elastomeric bonds that seal against the elements. These sealants excel in demanding industrial, transportation, and construction applications. Available in a wide variety of Shore A hardness, open times, and colors, they meet diverse application needs. Use a manual or pneumatic caulking applicator from 3M to dispense 3M adhesive sealant cartridges and 400 ml/600 ml sausages.
