Product Description
DTPMPA is widely used as a scale inhibitor in circulating cooling water and boiler water treatment systems. It is especially suitable for alkaline circulating cooling water, where it can function effectively without the need for pH adjustment. It is also applied as a scale inhibitor in oilfield injection water, cooling water, and boiler water containing high levels of barium carbonate.
When used alone or in compounded formulations, DTPMPA does not require the addition of a dispersant and still results in very low levels of sludge and deposit formation. In addition, it can be used as a peroxide stabilizer, chelating agent in textile printing and dyeing, pigment dispersant, oxygen delignification stabilizer, trace element carrier in fertilizers, and concrete additive.
It is also widely applied in papermaking, electroplating, metal pickling, and cosmetics. Furthermore, it can serve as a stabilizer for oxidizing fungicides.

Product Usage
DTPMPA is an excellent corrosion and scale inhibitor for circulating cooling water and boiler water systems. It is particularly suitable for closed-loop circulation systems such as power plant ash flushing water, as well as alkaline circulating cooling water, where it functions effectively as a scale and corrosion inhibitor without the need for pH adjustment.
It can also be used as a scale and corrosion inhibitor in oilfield injection water, cooling water, and boiler water with high barium carbonate content. In addition, it serves as a stabilizer for peroxide and chlorine dioxide-based fungicides.
When used alone or in compounded formulations, it does not require the addition of a dispersant, and still maintains very low levels of sludge and deposit formation.
