Application
PESA is a scale and corrosion inhibitor without phosphor and nitrogen. It has good scale inhibition and dispersion for calcium carbonate, calcium sulfate, calcium fluoride and silica scale. When combined with organophosphates, the synergism effects are obvious. PESA has good biodegradability. It can be widely used in circulating cool water system in case of high alkaline, high hardness and high pH value.
