G203 is made from inorganic materials.
Appearance: white powder.
Normal dosage: 1.0 % ~ 4.0 % (BWOC).
Increase early strength of cement stones efficiently and has no harmful influence on later strength increasing.
Suitable for oil / gas wells whose temperature is between 30℃~90℃ (BHCT).
Shorten the thickening time of cement slurry effectively and enhance the early strength of cement stone.
It makes cement slurry with a slight thixotropy when mixed with G203.

Low-density slurry formulation: G class cement, W/C: floalting beads ( Xingtai, Hebei ) = 10:1 (m/m), Water-solid ratio: 0.55, Water quality: distilled water, G203: 2.0% + USZ: 0.5% (BWOS).
Be packed with three-layer plastic bags, 25kg per bag.
Be kept away from moisture in transportation. If moistened, the additive dosage should be increased. It should be mixed with water when it is used. The worker should wear protective stuff to avoid contacting with skin while operating.
The Storage life time is two years.
