3M 051135-06520 Marine Adhesive Sealant, 10 Oz, Cartridge, White

The 3m Marine Adhesive Sealant, Fast Cure, is a high-strength polyurethane sealant designed for permanent bonding applications in severe marine environments. This product solves the critical problem of maintaining watertight integrity and structural bonds under conditions of constant vibration, shock, and exposure to saltwater.

• Durability: The tough polyurethane polymer resists weathering and saltwater, ensuring strong, long-lasting bonds both above and below the waterline.
• Efficiency: This fast-cure formula is tack-free in 1–2 hours and fully cures within 48 hours, significantly reducing vessel downtime during repairs or construction.
• Compatibility: The flexible elastomeric bond accommodates structural movement, absorbing stress from vibration, swelling, and shrinking without cracking or peeling.

This sealant is best for marine industry professionals, shipyards, and contractors performing permanent high-strength bonding on substrates like wood, fiberglass, and metal for applications such as deck-to-hull joints and hull fittings.

Comes in a 295 mL cartridge and offers a shear strength of 316 psi and a tensile strength of 1000 psi.
