DSP
Cement Dispersants
Additives that reduce slurry viscosity and improve pumpability of oil-well cement at low water-cement ratios.
Application
Primary cementing where tight W/C, high density or long placement requires dispersant chemistry matched to cement class and temperature.
Technical characteristics (quality certificate)
Typical values as stated on a mill quality certificate (passport) for a standard commercial grade. Actual lot values are confirmed in the COA / TDS for the selected manufacturer.

Cement Retarders
Additives that extend thickening time of oil-well cement slurries. Chemistry class must match temperature, cement type and slurry design.
