Technology News - Urethane Foam Stops Metal Corrosion At Salt Mine

The conveyor housing's corroded, exposed metal- deck was cleaned and cocooned to prevent renewed corrosion, at less than the cost of replacing the structure. And the process did not require operations to shut down. That was the result for Akzo Salt at its mine under Lake Erie's Whiskey Island, just off Cleveland, OH'S north coast. The exposed metal deck was on the underside of a covered, outdoor conveyor used to load mined road salt into boats.
