Aquahesive™ 5836
Aquahesive™ 5836 is a high-performance polyurethane adhesive for use with Champion Environ's anti-fouling subsea marker systems. It has a pot-life of 30-45 minutes and cures overnight, depending on the ambient conditions.
Polyurethane adhesives have limitations and care must be taken to ensure that the conditions under which Aquahesive™ is mixed and applied fall within the range of a minimum temperature of 10°C and maximum humidity of no more than 65-70%.
Aquahesive™ 5836's pasty consistency makes it ideal for use in vertical and overhead applications. Once cured, it is a tough, robust material with good general physical and chemical properties.
Aquahesive™ 5836 is a two component adhesive, supplied with the curative in a ready-to-mix form in disposable containers. Once, mixed, it has a long pot-life, making it ideal for bonding larger or multiple components in a short period of time. The mixed material cures to a harmless solid, making disposal straightforward. During use, personnel should wear PPE; gloves, skin protection and safety goggles.
Aquahesive™ 5836 has been tested and found to provide good adhesive strength to epoxy-coated steel, and to give excellent seawater resistance in ageing trials. Its rigid nature makes it appropriate for applications where a flexible adhesive might not be suitable. Aquahesive™ 5836 offers higher-thermal performance in service than conventional epoxy adhesives.
Aquahesive™ 5836 has a shelf-life of 12 months and should be stored in the conditions outlined in the data sheet.
Correct mixing, preparation and storage of Aquahesive™ 5836 is critical in ensuring the best possible performance. The following table outlines some of the more common problems that may be experienced when our installation procedure or data sheets are not followed:-
| Observed problem | Possible explanation | Solution |
|---|---|---|
| Bubbling in material | Humidity over 65% or too high mixing temperature | Attempt to work in conditions of reduced humidity and temperature |
| Poor mixing | Ensure two components are fully mixed before applying | |
| Soft material or soft-patches in material after cure | Poor mixing | Ensure two components are fully mixed before applying |
| Material out of shelf life or not stored correctly | Replace material with fresh adhesive | |
| Weak or brittle material after cure leading to poor bond | Poor mixing | Ensure two components are fully mixed before applying |
| Material out of shelf life or not stored correctly | Replace material with fresh adhesive | |
| Poor bond | Poor mixing | Ensure two components are fully mixed before applying |
| Material out of shelf-life or stored incorrectly | Replace material with fresh adhesive | |
| Contamination on surface | Ensure all surfaces are free of dirt or grease prior to application of adhesive |
Aquahesive™ 5836 offers a simple yet effective tried and tested solution for bonding Champion Environs' subsea markers.
