3M 14316 Marine Adhesive Sealant 4000 UV Black 10 oz Cartridge

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 above or below the waterline. This sealant is formulated for color stability and UV resistance, making it especially suitable for areas exposed to the sun and wherever flexibility is important.

Key Features:

• Becomes tack-free in as little as 22 minutes and typically cures in 24 hours
• Medium-strength adhesive allows for disassembly of boat parts without damage after long-term use
• Immediately paintable after curing
• Applies right from the container with no mixing required
• Dissipates stress caused by vibration and shock, won't crack under dynamic force, and resists salt, wind, weather and temperature extremes
• Compatible with ABS, aluminum, nylon, PVC, metal and wood materials

This versatile marine sealant bonds portholes, deck fittings, rub rails, screw holes, and stanchion supports while still allowing disassembly. Great for cosmetic seals over permanent adhesive material.
