• Multi-Purpose Marine Sealant: This medium-strength marine sealant bonds portholes, deck fittings, rub rails, screw holes, and stanchion supports while still allowing disassembly
• Excellent UV Resistance: A distinct ability to withstand the sun's rays allows it to excel in challenging outdoor industrial, transportation, and construction environments
• Color Stable: Maintains its color in applications above and below the water line
• Flexible Bonds: Durable elastomeric adhesion maintains joint movement and withstands stress caused by shock, vibration, swelling and shrinking
• Paintable When Wet: Forms a skin in 30-60 minutes but can be painted over with water-based paints immediately after application

3M™ Marine Adhesive Sealant Fast Cure 4000UV is a tough, flexible, semi-permanent marine sealant for strong, sharp seals on RVs, boats and other watercraft. Formulated for color stability and UV resistance, it is especially suitable for areas which are exposed to the sun and wherever flexibility is important. This marine adhesive is great for cosmetic seals over permanent adhesive material. It becomes tack-free in as little as 22 minutes, and it typically cures in as little as 24 hours. It is also immediately paintable after curing – so you can get right back out on the water. Marine grade sealant applies right from the container with no mixing required, and cures to form a firm, flexible, waterproof seal. Yet its medium-strength adhesive allows you to disassemble boat parts without damaging them after long-term use. It is ideal for use on wood, glass, gelcoat and fiberglass as well as many metals and plastics, and recommended for topside components like hatches, portlights, metal hardware as well as porthole seals. Like our 4200 marine sealant adhesive, it dissipates stress caused by vibration and shock, and won’t crack under dynamic force. It resists salt, wind, weather and temperature extremes just as effectively for years of worry-free enjoyment on the water.

Ideal for Marine Applications Above and Below the Waterline
Our 3M™ Marine Adhesive Sealant 4000 UV is a one-part adhesive sealant formulated to provide an exceptionally strong bond for harsh conditions as well as flexibility to combat vibrations, swelling, shrinking or shock common on boats or other marine applications. It is well-suited for many marine applications both above and below the waterline. Additionally, its superior UV resistance provides reliable long-term performance. Available in cartridge, sausage pack and drum volumes to meet your application needs.

Recommended Applications
■ Electrical assembly hatch■ Stanchion supports■ Thru-hull fittings and deck hardware■ Porthole frames■ Sealing screwholes
