This product is non-toxic, soluble in acidic solution, the effect of superior corrosion inhibition and good temperature, can inhibit the carbonate, sulfate scale formation in alkaline environment and elevated temperatures (210 degrees Celsius and above) resistance corrosion fouling than other organic phosphonic good. This product has a high calcium solubility Wang, PH = 10-11 in the ability to scale significantly better than ATMP / HEDP, scale capacity is 2-3 times the ATMP.HEDP of barium sulfate scale with good results
