mm wiiaa Compounders of metal cleaning specialties use Chelon DHG to control contaminating metal ions Chelon DHG is an aqueous solution of Sodium N, N-Dihydroxyethylglycinate. It forms metal chelates with heavy metal ions, but does not complex calcium or magnesium. Chelon DHG is therefore useful in applications where heavy metal ion control is desired in the presence of large amounts of water hardness ions. It is often used as a corrosion inhibitor in water cooling recycle systems or in alkaline
