HEDP•Na2 (Di Sodium Salt of HEDP)

Providing the powerful scale and corrosion inhibition of HEDP in a convenient salt form, HEDP•Na2 (Di Sodium Salt of HEDP) from Shandong Kairui Chemistry Co., Ltd. is a staple in the water treatment industry. This salt is a very good calcium carbonate inhibitor, a water hardness stabilizer, and a complexing agent for trivalent metal ions, closely mirroring the capabilities of its acid counterpart but with improved solubility and handling characteristics . It is an indispensable tool for maintaining the efficiency and integrity of cooling water systems, boilers, and oilfield operations.

The transition to the sodium salt form does not compromise the performance of HEDP. HEDP•Na2 still provides excellent threshold inhibition, preventing scale deposition by disrupting crystal growth. It effectively stabilizes hardness ions in solution, allowing systems to operate at higher cycles of concentration and reducing water consumption. Its h3 chelating power for ions like iron is vital for preventing the precipitation of ferric deposits, which can foul equipment and act as a site for corrosion. The product’s stability is such that selected grades are even certified under NSF/ANSI/CAN 60 for drinking water applications, a testament to its safety and reliability .

Kairui Chemical offers HEDP•Na2 in various concentrations and forms to suit specific customer needs. Its ease of use and reliable performance make it a foundational product for countless water treatment formulations. By choosing Kairui Chemical's HEDP•Na2, you are selecting a trusted, proven solution that delivers robust protection against scale and corrosion, ensuring the long-term, efficient operation of your critical assets.
