Structural formula:

I. Product Property

PASP is a water soluble polymer. It is a green water treatment agent, with properties of non-phosphor, non-pollution and fully biodegradation. PASP has excellent good chelation to ions and possesses double virtues of corrosion and scale inhibition. PASP has good scale inhibition on calcium carbonate, calcium sulfate, barium sulfate, calcium phosphate, etc. Its scale inhibition rate for calcium carbonate is 100%. Moreover, PASP has dispersion and corrosion inhibition properties to metal equipment.

PASP is an alternative of phosphor-containing Water Treatment Chemicals with the effect of avoiding water system eutrophication and second pollution.

III. Scope of Application

1. PASP can be used as scale and corrosion inhibitor in industrial circulating water, boiler water, reverse osmosis, oilfield water and desalination. The effects will be even better than ordinary organophosphines when used in high hardness, high alkaline, high pH value and high concentration index. When built with PBTCA, the synergism is obvious.

2. Due to its green and non-pollution to environment, PASP can be used as accessory ingredients in daily and fine chemicals.

3. PASP can be used in agriculture as nutrient absorption intensifier to improve the production of vegetable, melon and fruit, and flowers. When used together with pesticide, its effects will be improved.

IV. Package and Storage

It is usually packed in 25kg or 200 kg plastic drum or that as determined by users and can be stored for ten months in shady and dry place under room condition.
