- C-G211Sis a copolymer well cement fluid loss agent. Assemble of AMPS, well anti- temperature and anti-salt as main monomer and others monomers of anti-salt. Molecules contain quantity of perssad of －CONH2、－SO3H、－COOH with strong absorption, have important function on anti-salt, anti-temperature, absorb free-water, fluid losing.
- C-G211S can be widely used in various kinds of cement slurry system, good compatibleness with other additives.
- C-G211Scan be used in a wide temperature range, anti-temp to 180℃, well flowability, stable, few free liquid, no- coagulation delaying, intensity grow fast. It can be used to make cement slurry system with fresh water or salt water, no specific requirement to water quality of making up slurry.
