DTPMP (DETPMP) acid is innocuous, easy to be dissolved in an acid solution. It has an excellent scale and corrosion inhibition and good thermal tolerance ability.

DTPMP (DETPMP) can inhibit the scale formation of carbonate, sulfate, and phosphate. On the situation of the alkali environment and high temperature (above 210℃), DETPMP has a better scale and corrosion inhibition effect than other organophosphines.

DTPMP can be used as scale and corrosion inhibitor in circulating cool water system and boiler water. And especially in alkali circulating cool water system without additional pH regulation, DETPMP can also be used in oilfield refill water, cool water and boiler water with a high concentration of barium carbonate.

When used alone, little scale sediment is found even none of the dispersant is used. DTPMP (DETPMP) can also be used as peroxide stabilizer, the chelating agent in the woven & dyeing industry, the pigment dispersant, microelement’s carrying agent in fertilizer and concrete modifier.

In addition, DTPMP is used in papermaking, electroplating, acid cleaning and cosmetics.
