Summary
DOC-G86S is a type of fluid loss additive that the main component was AMPS polymers, which has good universality and can be used in a group of slurry system.
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, Salt Water, Sea Water.
