The main ingredient of GR-S is styrene-butadiene latex.
GR-S latex has a good performance of anti-gas leak.
GR-S is compatible with all kinds of oil well cements and most of other additives.
GR-S has good salt- resistance ability, and can be used in salts cement slurry.
GR-S has auxiliary function in terms of fluid loss control ability, which can cut down the dosage of fluid loss control additives.
Common dosage is 3% ∼ 10% (BWOS).
Cement slurry which used GR-S latex has good stability, uneasy breaking emulsion, and free fluid closes to zero.
The latex slurry’s thickening transition time is short, close to right-angle thickening.
