Subsea Industries has announced a new product for filling and building up a corroded and pitted steel surface to its original form prior to recoating with Ecoshield. Ecofix® is said to be as tough as the steel itself, machinable, and can be used to repair most pitting or corrosion damage on rudders, stabilizer fins, thrusters and other underwater gear.
The new product restores steel to its original shape after cavitation or corrosion damage. It is designed to be used prior to recoating with Ecoshield, the rudder protection coating, which protects against future similar damage.
Subsea Global say: “When a rudder or other piece of underwater ship gear has not been properly protected, the surface will become corroded. Cavitation damage can cause severe pitting. The steel needs to be restored to its original shape with a smooth surface prior to recoating. This is where Ecofix comes in. It is a superior, tested and proven filler. Because it uses the same basic resin as Ecoshield, the coating can be applied just one hour after the filler. The bonding and hardness are extraordinary. This is the effective alternative to metal facing or very expensive alternative fillers. And because it is part of the Ecospeed/Ecoshield family, it is fully compatible with the coating.
“Ecoshield gives permanent protection against cavitation damage for rudders. The glassflake reinforced coating protects the rudder for the service life of the ship without need for recoating or major repair and comes with a ten-year guarantee. It is the only coating known to fully protect a rudder from all cavitation damage for the remainder of a vessel’s service life. Now with the launch of Ecofix, the repair work needed on the underlying steel can be done effectively and economically prior to the Ecoshield application.”
Ecoshield and Ecofix are also suitable for stabilizer fins, thrusters, nozzles and other underwater ship gear which need special protection from corrosion.
