GR-L is made of styrene butadiene latex mainly.
Good anti gas channeling performance.
Has good compatibility with various of oil well cements and other additives
.
Has good salt tolerance, can be applied to salt water slurry.
Can significantly reduce the amount of water reducing agent with reducing
water loss property.
Normal dosage: 3%～10% (BWOS).
Has good stability, not easy to demulsificate.
Free fluid is near to zero.
Cement slurry thickening transition time is short, close to right angle
thickening.
