HEDP,HEDPA, HEDP.Na,HEDPNa2,HEDPKx

HEDP/HEDPA is an organophosphoric acid corrosion inhibitor.

HEDP/HEDPA can chelate with Fe, Cu, and Zn ions to form stable chelating compounds.

HEDP/HEDPA has good chemical stability under high pH value.

HEDP/HEDPA can be used as cleaning agent in electronic fields and as additives in daily chemicals.

HEDP/HEDPA can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular

HEDP/HEDPA can be used as cleaning agent in electronic fields and as additives in daily

HEDP.Na is an organophosphonic acid corrosion inhibitor.

HEDP.Na can chelate with Fe, Cu, and Zn ions.

HEDP.Na has good scale and corrosion inhibition effects.

HEDP.Na is suitable for acidic scale inhibitor and detergent, can be used for metal surface treatment.

HEDPNa2 is an organophosphonic acid corrosion inhibitor.

HEDPNa2 it can chelate with Fe, Cu, and Zn ions, it can dissolve the oxidized materials

HEDPNa2 can form six-ring chelating compounds with metal ions in water system

HEDP.Na4 is the sodium salt of HEDP.

HEDP.Na4 is an good scale inhibitor for calcium carbonate.

HEDP.Na4 it can be used in low pressure boiler water system, circulating water system, industrial and municipal cleaning water system and swimming pool.

HEDPNa4 is used as detergent for metal and nonmetal.

HEDP.Kx is the potassium salt of HEDP

HEDP.Kx has better dissolution ability than that of sodium salt under neutral condition

HEDP.Kx is a good scale inhibitor for calcium carbonate, HEDP.Kx can be used in metal corrosion inhibitor, antifouling agent of swimming pool, metal cleaning, volume cleaning, iron dust controlling, metal pretreatment, low pressure boiler water treatment and circulating water treatment, etc.
