When the sea tests performance. LOCTITE delivers. Adhesives, sealants and coatings engineered to withstand the toughest marine environments.
Marine vessels operate in highly demanding environments where materials and assemblies are constantly exposed to saltwater, humidity, extreme temperatures, vibration and dynamic mechanical loads. These conditions accelerate corrosion, promote condensation, increase noise and vibration, and put significant stress on structural joints, equipment and onboard systems. At the same time, shipyards and marine manufacturers face pressure to reduce weight, improve efficiency, ensure long‑term durability and comply with strict safety and certification requirements. Addressing these combined challenges requires reliable, marine‑ready solutions that deliver strong, watertight bonding, thermal and acoustic protection, and consistent performance throughout the vessel lifecycle.
From rigid to flexible, the solutions are organised into five types. First, in Epoxy, LOCTITE® EA 3421, LOCTITE® EA 9461, LOCTITE® EA 9466, and LOCTITE® M-121-HP provide very high-strength, rigid structural bonding.

LOCTITE® SF 7515 further enhances surface protection and bonding performance by providing extended protection after sandblasting or grinding prior to painting, allowing larger areas to be treated before applying new coating layers and helping to reduce overall docking time.
And lastly, in coating, LOCTITE® SF 7505 is applied to protect metal surfaces against corrosion, ensuring long-term durability.
Every vessel is built, equipped and maintained through a wide range of critical applications, each exposed to harsh marine conditions. From surface preparation and structural assembly to technical installations, insulation, glazing and onboard maintenance, these applications must withstand moisture, vibration, thermal stress and mechanical loads over time. Henkel supports marine professionals by addressing these real‑world applications with engineered adhesive, sealing and coating solutions that improve durability, efficiency, safety and long‑term performance throughout the entire vessel lifecycle.

Henkel supports marine construction with bonding and coating solutions that replace or reduce welding and mechanical fastening. Adhesives enable bonding of different materials and structures without heat, deformation or drilling. This supports faster assembly and can reduce noise and enable a lighter, more efficient vessel design, even after hot work has been completed.
Modern marine and yacht design increasingly relies on advanced glass bonding solutions that can withstand harsh marine conditions. Henkel supports a range of glass bonding applications. Our proven, reliable systems are suitable for glass and polycarbonate. They combine the necessary strength with the desired flexibility, helping to create safer and more aesthetically pleasing glass structures on vessels. Selected solutions are also certified by Lloyd’s Register, supporting compliance with recognized marine industry standards.
Marine technical installations require reliable fastening, precise alignment, and long‑term vibration resistance. Henkel solutions support the chocking, alignment, and installation of main engines, pumps, and generators, while advanced threadlocking and pipe sealing technologies prevent loosening and leaks under dynamic loads—ensuring secure installations, improved reliability, and simplified maintenance. For interior and confined environments, we also offer safer adhesives and cleaning solutions designed to prioritize operator health and safety without compromising performance.
Interior and exterior applications demand strong yet flexible bonding solutions that support lightweight construction, design freedom, and durability. Henkel provides a wide range of adhesives and sealants for bonding rails, panels, furniture, and structural elements across decks, hulls, and interiors. With advanced coatings and materials that enhance thermal performance, reduce condensation, and improve noise and vibration damping, vessels achieve greater comfort and efficiency with less complexity and weight. Many solutions are developed to meet marine industry standards, with selected products certified to IMO requirements for safety, fire performance, and durability.
Daily onboard maintenance requires reliable products that are safe for the crew and the environment. These products help repair and protect onboard equipment. By using the right materials such as our LOCTITE® anaerobic products equipment can achieve a longer service life. Many of our products can be ordered through the IMPA system.
Effective bonding in marine environments starts with proper surface preparation. Hulls, decks and superstructures are often contaminated by rust, oils, resins, salt residues and dirt, all of which can compromise adhesion. Henkel offers safe, compliant cleaning and surface treatment solutions, including water‑based products and wipe alternatives to solvents. These solutions improve adhesion performance while enhancing worker safety and sustainability.
