Oil field, Paints, pigments & paper Industries. Textile as peroxide bleach stabilizer & Leather Auxiliary Chemicals. DTPMPA 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, it can also 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. can also be used as peroxide stabilizer, chelating agent in woven and dyeing industry, pigment dispersant, microelement's carrying agent in fertilizer and concrete modifier. In addition, it is used in papermaking, electroplating, acid cleaning and cosmetics.
