HEDP Series


HEDP - 1-Hydroxy Ethylidene-1, 1-Diphosphonic Acid

HEDP  is an organic phosphorus acid, scale & corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. HEDP is widely used as scale inhibitor, deflocculant, sequestrant and water stabilizer in cooling water systems. HEDP has a greater pH value and is even stable under high temperature. HEDP is a highly effective chelating agent and sequestering agent.
HEDP is a popular EDTA substitute.
