Structural Formula (Mw about 600):
Britequest PAPEMP has high calcium tolerance and good scale inhibition effects, especially on silica scale, calcium carbonate, calcium sulphate and calcium phosphate. It stabilizes metal ions such as Zn, Mn and Fe. Britequest PAPEMP is active in conditions of high water hardness, high alkalinity, high salt concentrations, high turbidity, high temperature and high chlorine, chlorite and biocide concentrations. For less stringent conditions we offer our standard phosphonic acids such as Britequest HEDP and Britequest ATMP.
It is used as scale and corrosion inhibitor in cooling water systems, boilers, reverse osmosis, multistep flash vaporization systems and oilfields. In agriculture Britequest PAPEMP is a nutrient absorber. And in textile dyeing it is a color transfer inhibitor, as alternative to EDTA, DTPA, NTA.
