Military tests underwater glue used to fix damaged dinghies in extreme conditions
An underwater glue has been successfully trialled in Portsmouth, meaning the adhesive could soon give the military an operational edge.
The glue, which mimics the way a mussel sticks to a rock, will allow military personnel to repair wetsuits, damaged dinghies, and other equipment rapidly in extreme environments.
It will also make it easier to repair bridges under the waterline and could lead to savings by allowing for repairs during deployment.
"This unique approach, inspired by nature, demonstrates how the UK is becoming a hotbed for pioneering defence technology," Defence Procurement Minister Maria Eagle said.
"Our scientists are working with industry to unlock emerging technologies, finding new ways to protect the military personnel who keep our nation safe, at home and abroad."
The glue was developed by the MOD's Defence Science and Technology Laboratory (Dstl) and biotech firm Zentraxa.
British Army divers tested it by gluing several items to an underwater steel wall at Horsea Island.
The adhesive was tested in simulated sea water in the laboratory and performed well on wet out-of-water surfaces.
The glue could also be used in other areas beyond defence.
"We have taken inspiration from natural organisms that can stick underwater like the marine mussel and then tried to exploit that biochemistry into a real-world setting," Zentraxa's chief technology officer, Martin Challand, said.
"This is a major milestone for our product – this is what we have dreamed of. It is extremely rewarding to see it being used and knowing that in the future it could save lives, and it is fantastic to be working together across sectors like this."
Dstl gave £300,000 to support the project and will work with other areas of the defence space to further develop the glue.
