Summary
Fluid Loss Additive include DOC-410L (standard) and DOC-410L-W (anti-freezing).
The product was suitable for a wide temperature range, and its high temperature resistance up to 230℃. The cement slurry with this product had good fluidity, stability, less free water, no retarded effect, rapid strength development and has no special need to slurry-mixing water. Used in both Fresh Water and Salt Water.
