BDC-205 is a latex additive for cement that controls fluid loss, makes cement gas-tight, more elastic (less shattering on perforating), and promotes better bonding. To control fluid loss, BDC- 205 decreases the porosity and permeability of the filter cake without damaging freshwater- sensitive formations.


Suitable for all cement slurries and commonly used additives such as retarders, salt, dispersants, bentonite, gilsonite, and pozzolans from 60 to 230°C.

Can be used in all kinds of mix waters: fresh, seawater, up to 8 percent calcium chloride water, and up to saturated sodium chloride water.


  • Versatile additive that can be used with all common cement additives and various mix waters.
  • Intensifies and stabilizes commonly used retarders.
  • Provides gas migration control.
  • May increase the settling tendency of the slurries, but the addition of additives, like bentonite,can control it


Typical concentration range is 0.5 to 2.0 percent by weight of cement (BWOC).
