3M™ 5200 Marine Sealant/Adhesive
3M™ 5200 Marine Sealant Adhesive is an extremely fast curing, one-part polyurethane that chemically reacts with moisture in order to provide very strong and flexible adhesive bonds when working with wood and fibreglass. Thanks to its polyurethane adhesive it can form watertight and weather-resistant seals that can be applied in working on boating hardware above and below the waterline.
