DOSR™ 70 MT Synthetic Retarder

Mid Temperature Synthetic Retarder

DOSR™ 70 MT is a synthetic cement retarder based on proprietary acrylic polymers


  • DOSR™ 70 MT Synthetic Cementing Retarder recommended in controlling the setting of the cement slurry in applications with bottom hole circulating temperatures (BHCT) up to 250°F (121°C) in freshwater slurries and up to 350°F (177°C) in saturated saltwater slurries. The performance of this additive is improved by cement retarder intensifiers

  • DOSR™ 70 MT has a typical loading rate of 0.1 to 2.0% by weight of cement (bwoc).

  • DOSR™ 70 MT also acts as a dispersant in the cement slurry.

  • bottom hole circulating temperatures (BHCT) up to 250°F (121°C) in freshwater slurries and up to 350°F (177°C) in saturated saltwater slurries.
