3M™ Marine Adhesive Sealant, 5200, mahogany, 11 fl oz (296 mL), cartridge

The 3M™ Marine Adhesive Sealant 5200 is a single-component, high-strength, moisture-curing, gap-filling polyurethane for permanent bonding of wood, gelcoat and fibreglass. It cures to form a firm, rubbery, waterproof seal on joints and boat hardware, both above and below the waterline. In addition, our marine adhesive sealant is flexible and allows for structural movement and dissipation of stress that may be caused by vibration, swelling, shrinking or shock. Available in both cartridge and sausage packs to meet your application requirements.

Stress caused by shock, vibration, swelling or shrinking is effectively absorbed. Check the bonding and sealing jobs this product can handle for you: fibreglass deck to fibreglass hull, wood to fibreglass, portholes and deck fittings, motors on fibreglass transoms, under mouldings, hull seams above and below water line, centre board trunk joints, between struts and planking, stern joints, deck housing, etc. Easy to apply with manual caulking gun. Remains workable with trowel or spatula up to four hours after application. Won't sag or flow in vertical or horizontal seams.
