For Marine
Aury Africa offers a dedicated range of marine-grade sealants designed to withstand the extreme conditions of maritime environments. From shipbuilding and vessel maintenance to dockside infrastructure and offshore platforms, these sealants are formulated to perform under constant exposure to saltwater, UV radiation, high humidity, and temperature fluctuations. Whether sealing hull joints, bonding deck components, or protecting structures against water ingress, Aury’s marine sealants provide long-lasting, flexible, and weather-resistant performance.
What Are Sealants for Marine?
These sealants adhere to a wide variety of marine substrates including aluminium, fibreglass, steel, wood, and composites. Once cured, they remain permanently elastic, allowing them to absorb movement caused by hull flexing, temperature changes, or mechanical load without cracking or delaminating. In addition to sealing, many of our marine products also serve as structural adhesives, offering high bond strength for deck fittings, panels, and bulkhead installations.
Performance in Harsh Conditions
Aury’s marine sealants are specially formulated to resist deterioration caused by salt, sun, and surface flexing. They exhibit excellent UV resistance, non-yellowing colour stability, and a high level of tear and abrasion resistance. Once applied, the sealants create a tough yet elastic barrier that prevents water ingress, resists fungal growth, and absorbs shock and vibration.
These sealants cure without shrinkage, are paintable after application (depending on type), and have excellent resistance to fuel, oils, and common cleaning chemicals used on ships and marine structures. Their long open time allows for repositioning or adjustment during installation, and once cured, they remain effective for many years, even in continuously wet or submerged areas.
Applications
Aury’s sealants are used extensively in shipyards, harbours, and offshore installations for both construction and maintenance purposes. Common applications include sealing deck seams, porthole frames, hatch covers, and marine windows; bonding fairings, trim, and interior panels; and sealing service penetrations, electrical conduits, and vent flanges. In offshore energy projects, these sealants are used to protect equipment housings, wind turbine bases, cable ducts, and steel platform joints from saltwater corrosion and mechanical fatigue.
For floating structures or wave-impacted areas, the sealants’ flexibility ensures continued performance without losing adhesion or becoming brittle. Their waterproofing capability helps protect sensitive electrical systems, structural interfaces, and internal compartments from water ingress and condensation-related damage.
Product Availability and Support
Aury supplies marine sealants in cartridge, sausage, and bulk packaging formats suitable for both workshop and on-site application. We provide full technical data sheets, curing profiles, and chemical compatibility charts to assist in product selection. Our technical support team can advise on surface preparation, sealant selection for submerged vs non-submerged use, and application best practices to ensure optimal performance and product longevity.
In addition to product supply, Aury offers field-based guidance for marine projects involving sealant use, including retrofit works, vessel refurbishments, and new infrastructure builds. Where required, custom packaging, colour-matching, and application tools are available to support installation teams and contractors.
Trusted by Marine Professional
Aury Africa’s marine sealants are trusted by port authorities, vessel operators, shipbuilders, and offshore contractors for their strength, durability, and ease of use. They are used across tugboats, ferries, pontoons, barges, naval vessels, harbours, and floating infrastructure systems. Whether maintaining a watertight seal on deck or securing a structural joint below the waterline, Aury’s marine-grade sealing solutions ensure long-term protection in some of the world’s most challenging environments.
