Product Q&A

Q:What are the main applications of HEDP-Na4?

It is widely used as a scale and corrosion inhibitor in circulating cool water systems, medium and low pressure boilers, and oil field water pipelines across power, chemical, and metallurgy industries.

Q:Is HEDP-Na4 suitable for use in cold climates?

Yes, the solid white powder is soluble in water and easily deliquescent, making it suitable for use in winter and freezing districts.

Q:What is the shelf life of this product?

We normally list 2 years as the shelf life in our COA, but the real shelf life can be slightly longer than 2 years if stored in good condition (sealed bags, away from direct sunlight and moisture).

Q:How does HEDP-Na4 protect metal surfaces?

It is an organophosphonic acid scale and corrosion inhibitor that can form stable complexes with Fe, Cu, and Zn ions, helping to dissolve oxides on metal surfaces.

Q:What are the payment terms for this product?

We accept LC, T/T, D/P, Western Union, and Money Gram as terms of payment.
