AQUASIGN is known for our unique anti-fouling subsea markers, designed to enhance safety and reduce operational costs by offering a guaranteed highly visible equipment identification solution.
But did you know we also offer a range of high-performance structural adhesives that are specially formulated for the harsh environments expected in the offshore industry? Suitable for both topside and subsea.
Industry-approved offshore adhesives that offer environmental, economic and performance advantages over traditional welding, is becoming increasingly popular.
During design, fabrication and modification of offshore equipment, there are a number of structural joining tasks that in some cases mechanical methods of bonding are not suitable; material combination, thickness of substrates, aesthetic reasons or to avoid tarnishing of the equipment’s surface. However, finding an industrial adhesive that meets demanding offshore standards can prove difficult.
Our non-toxic adhesives offer excellent mechanical strength, temperature resistance, long-term performance and are economically viable to replace traditional mechanical solutions. The adhesives are a proven fixing solution with our Aquasign® subsea markers, boasting a worldwide track record and 60-year guarantee based on vigorous third-party testing.
We have two options:
- Biohesive® 225
Biohesive® 225 is a silicone RTV adhesive that can be used in geographical locations with high temperatures and humidity, making it ideal for seawater-resistant bonding and corrosion protection.
Supplied as a single component in 310ml cartridges, the application process is very straight-forward relying on the atmospheric moisture to cure and utilising a standard caulking gun. Biohesive® has shown excellent resistance to natural ageing, including exposure to UV, weathering and salt mist.
- Aquahesive™ 5836
Aquahesive™ 5836 is our two-component polyurethane adhesive, designed for structural bonding. Supplied with a curative in a ready to mix form, it is a tough robust material that boasts excellent physical and chemical properties.
Dependent on ambient conditions, it has a long pot life making it ideal for bonding large or multiple components within short timescales. Aquahesive™ is suitable for use over a wide temperature range and relative humidity, and has shown excellent resistant to seawater in ageing trials.
Aquahesive™ 5836 also has a track record of being used as an underwater glue, mixed topside and applied by a diver in shallow waters to for retrofit subsea bonding or to create a water-tight seal.
