1-Hydroxy Ethylidene-11-Diphosphonic Acid (HEDP

Details

An organic phosphonic acid scale/corosion inhibitor. Chelates metal ions (Fe, Cu, Zn), dissolwes metal oxides Effectiwe up to 250eC, stable at high pH, resistant to hydrolysis and decomposition. Good chemical/chkorine resistancecompared to other phosphonates Foxms stable chelates with Ca't, providing scale inhibition and a threshold effectSynergistic with other water treatment agents 1, Solid is high-purity, suitable for cold climates, also for electronics deaning and daily chemicals. 2. Used for scale/comosion inhibition in coolinq water, low/medium pressure boilers, oillheld water injection, and pipelines. Also used in textiles as a deaner, peroxde staoilizer, dye fixative, non-cyanide electroplating complexing agent, and radioactive element carrier in phamnaceuticals.
