HR®-5 Retarder

HR®-5 additive is a chemically modified lignosulfonate that retards the setting of cement. It is designed for use in wells with circulating temperatures between 125°F (52°C) and 206°F (97°C) – 290°F static (143°C).

HR-5 additive is compatible with the following:

  • Fresh or saltwater slurries
  • Most cement additives
  • All API cements
  • Bentonite cement
  • Pozmix® A cement

HR-5 additive provides the following benefits:

  • Increased concentrations of HR-5 additive enhance the predictability of cement thickening times.
  • Decreases the danger of over-retarded slurries at the top of a long cement column.
  • Provides early cement strength development.
  • Helps displace slurries at high rates while maintaining formation pressure.

Summary Summary HR®-5 Cement Retarder
HR®5 additive is a chemically modified lignosulfonate that retards the setting of cement. It is designed for use in wells with recirculating temperatures between 125° and 206°F (290°F static).
Summary Summary Retarders
Retarder additives are used to increase the set time of cement slurries or to increase pumping time.
Summary Summary HR®-5 Retarder
A chemically modified lignosulfonate used to retard the setting of all classes of cement and Pozmix® cement, provides more predictable thickening times than HR-4 and can be used at bottomhole circulating temperatures up to 210°F (99°C), as a secondary effect HR-5 retarder acts as a slight dispersant
