    Technical Data Sheet

    HEDP·Na4 is the sodium salt of HEDP and is an excellent inhibitor of calcium carbonate scale. HEDP·Na4 is mainly used for metal corrosion inhibition in low-pressure boiler water treatment, circulating water treatment, industrial and municipal clean water, and swimming pool sterilization.
    HEDP·Na4 is a white powder solid, easily soluble in water, non-hygroscopic, easy to transport, and suitable for use in severe cold conditions. HEDP·Na4 belongs to the organic phosphonate scale and corrosion inhibitor, which can form stable complexes with various metal ions such as iron, copper, and zinc, and can dissolve oxides on the metal surface. It still has a good corrosion and scale inhibition effect at 250°C.
    HEDP·Na4 is widely used in industrial circulating cooling water, low-pressure boilers, oil field water injection, and oil pipelines in power, chemical, metallurgy, fertilizer, etc.; HEDP·Na4 can be used as a metal and non-metal cleaning agent in the light textile industry, a peroxide stabilizer and color fixer in the printing and dyeing industry, a cyanide-free electroplating complexing agent, and a daily chemical additive.
