Usage
HEDP is a leading chemical for controlling water quality in industrial systems.
It prevents the precipitation and deposition of mineral scale (such as calcium carbonate and calcium sulfate) in pipework.
It forms a protective layer on metal surfaces to mitigate corrosion.
In consumer goods, Etidronic Acid is used primarily as a chelating and stabilizing agent.
