The marine environment poses extreme challenges for materials. This is particularly true for underwater components in the water near submarine and ships with cathodic protection systems. TRI Austin’s BondcoatTM Non-Conductive Coating (NCC), in conjuction with our TRI Seal Plus TM sealant, offers significant life extension to underwater polymer to metal bonds, dramatically extending the life of underwater electrical connectors. We are developing and qualifying a new product for the same purpose that can be brush applied. Also, we are formulating new urethane molding compounds for this environment that eliminate the highly toxic components in legacy materials. We are also developing new highly waterproof materials for towed array hose walls, and improved lightweight high performance tow cables.
