DOSR™ 80 HT Synthetic Retarder


High Temperature Synthetic Retarder

Description: DOSR™80 HT Retarder contains a proprietary complex blend of low molecular weight polymers and hydroxycarboxylic acids.


  • DOSR™80 HT Retarder is a synthetic organic based high temperature cement retarder for use from 250°F to 350°F bottom hole circulating temperatures (BHCT). Where longer Total Thickening Times (TTT) are desired at BHCT’s greater than 350°F the cement retarder intensifier can be used in conjunction with DOSR™80.

  • DOSR™80 HT Retarder can be used with all cements and most common cement blends.

  • DOSR™ 80 concentrations are typically 20% to 40% less than other retarders often offsetting any additional cost.
