DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA is an excellent inhibitor for mineral deposits (for example CaCO3, BaSO4, SrSO4) .and a powerful complexing agent. DTPMPA inhibits scale formation at extremely low (ppm) dosage levels, sub-stoichiometric concentrations calculated on hardness of water. On situation of alkali environment and high temperature (above 210℃) , wide range of PH Values, DTPMPA has better scale and corrosion inhibition effect than other organophosphines.

DTPMPA can be used for scale and corrosion inhibitor in circulating cool water system, boiler water, especially in alkali circulating cool water system without additional pH regulation.
DTPMPA can be used in oilfield refill water, cool water and boiler water with high concentration of barium carbonate. When used alone, little scale sediment is found even none of dispersant is used.
DTPMPA can be used for peroxide stabilizer, chelating agent in woven & dyeing industry, pigment dispersant, microelement’s carrying agent in fertilizer and concrete modifier.
DTPMPA is used in papermaking, electroplating, acid cleaning and cosmetics.
