Dequest 2000 is a general purpose, cost-effective scale inhibitor based on amino tri methylene phosphonic acid.
Dequest 2000 provides corrosion inhibition with zinc and phosphates and is a good chelant.
Dequest 2000 is applied in cooling water treatment, boiler water treatment, industrial and institutional cleaning, oilfield water treatment and general purpose metal ion control.
DEQUEST 2000, specifically developed for applications in which chlorides could cause corrosion of stainless steel (stabilisation of peroxides solutions).
Corrosion occurs when a metal is attacked by oxygen in water; this is a near-universal problem in water systems.
Phosphonates act as Cathodic corrosion inhibitor and in combination with zinc or phosphates, are highly effective in inhibiting mild steel corrosion.
The effect of these combinations is much greater than the effect of any component by itself.
Synergistic corrosion inhibition is also seen with molybdate, nitrate and most of the other corrosion inhibitors and combinations.
DEQUEST 2000 has been found to be particularly effective in systems where efficient corrosion control is required.
Dequest 2000 is a chelating agent forms stable complexes with metal ions such as iron, copper, and zinc.
Inorganic polyphosphates tend to hydrolyze to orthophosphate.
This reversion affects scale inhibition properties and can lead to calcium orthophosphate scale formation.
Dequest 2000 series of phosphonates are hydrolytically stable over a wide range of pH values and operating temperatures.
This superior resistance to decomposition is a major advantage of the Dequest phosphonates.
The presence of oxidising biocides (hypochlorous, hypobromous acids, ozone, chlorine dioxide) will affect the performance of Dequest 2000.
Therefore, appropriate formulatory and application con-siderations have to be taken.
