Antiscalant
HEDP CAS No 2809-21-4Hydroxyethylidene Diphosphonic Acid (HEDP) is a versatile organophosphonic compound with core functions:
- Scale inhibition: Effectively prevents scale formation (e.g., calcium carbonate, calcium sulfate) in industrial water systems (boilers, cooling towers) by chelating metal ions.
- Corrosion protection: Forms a protective film on metal surfaces (steel, copper), shielding them from corrosion in water treatment and metalworking fluids.
- Chelation: Strongly binds to metal ions (Fe³⁺, Cu²⁺, Zn²⁺), used in electroplating (to stabilize bath solutions) and detergent formulations (to enhance cleaning efficiency).
- Other uses: Applied in oilfield water treatment (to control scale/corrosion) and as a stabilizer in textile dyeing processes.
