Description
- C-G411S is a copolymer well cement fluid loss agent. Assemble of AMPS and N,Ndimethylacrylamide （DMAA）,well anti- temperature and anti-salty as main monomer and others monomers of anti-salty. 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-G411Scan be widely used in various kinds of cement slurry system, good compatibleness with other additives.
- C-G411Scan be used in a wide temperature range, anti-temp upto 230℃, well flowability, stable, few dissociated liquid, non-retard, 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.
