According to Dave Welkening, Rivertop’s product manager for corrosion sciences, the Headwaters product is chemically modified sugar that is derived from dextrose. The product, he said, has a high affinity for metal surfaces. “Basically, we have a proprietary formulation which combines a few ingredients with this oxidized sugar to create a product we sell as a corrosion inhibitor for the deicing market,” Welkening said. “Being derived from…agricultural sources, it’s also biodegradable, so it replaces products which are detrimental to watersheds. It is a very effective corrosion inhibitor, but it also has a very small environmental footprint. It reduces corrosion by approximately 70 percent compared to straight uninhibited salts.”
