Britequest ATMP and the little higher priced Britequest HEDP are is the most common of phosphonic acids. Britequest ATMP is an excellent chelating agent, inhibiting scaling right from the start. Especially effective on CaCO3. At higher concentrations, Britequest ATMP is anti-corrosive. It is chemically stable and hard to hydrolyse.
Applications are industrial cooling water, boilers and oil refineries. In the dye industrie, because of its high purity, Britequest ATMP is used to treat metal surfaces. Normally the 50% solution is used. The solid Britequest ATMP-95% is suitable in regions with temperatures below zero.
In more extreme conditions of high alkaline, high water hardness, high temperature, high salt concentrations and high turbidity, it is advised to use specialty products such as Britequest PAPEMP.
For chlorine stability, Britequest PBTC is preferred.
