The Most Important Component of any Marine Adhesive or Sealant: Trust.
Whether you’re boatbuilding, maintaining a fleet or repairing a single watercraft, you expect your adhesive sealants to create watertight seals. But the right ones will do much more. They will resist weathering, shock, vibration, swelling and shrinkage over time. It also means they will earn your trust. 3M designs quick-applying, long-lasting adhesives and sealants for specific conditions – below the waterline, topside and everywhere in between, on virtually any surface you can find on your boat.

The toughest sealants on the sea
Whether you’re bonding trim, toe rails, fittings or fiberglass deck components, or sealing thru-hulls, hatches, hinges, trunk joints or almost anything else on a marine vessel, 3M has an adhesive sealant that’s proven to the task. Our products have set the standard for marine excellence for more than 50 years, and they now include a new generation of advanced polyurethane and silane-modified polymers (SMPs) that further expand their range and effectiveness.
3M Marine Adhesive Sealants are specifically designed for the rigors of the marine environment, bonding or sealing everything from wood, metal and glass to gelcoat and most plastics—including fiber-reinforced plastic (FRP). Boaters have no better friend on the water.

ACTUALIZACIÓN (FEBRERO 2023): No recomiendo comprarlo. El producto es bueno pero solo pude usarlo 1 sola ocasión y el 99% restante del producto no pude usarlo. Cuabdo lo abrí limpié la boca y lo cerré con su tapadera. Al intentar usarlo de nuevo la tapadera estaba rota, supongo que se hizo presión al secar el producto de la punta. No hubo forma de retirar el producto seco dentro de la boquilla...intenté con desarmador, con un tornillo, con acetona para suavizarlo y nada dio resultado. Los objetos traspasan el sellador, pero al apretar para que salga producto se bloquea con el que está seco y no sale nada incluso usando mucha presión...un completo fiasco ¡Tengo el tubo lleno de producto pero es inutilizable! ¡Dinero tirado a la basura!
Je recommande.
