- G203A is made from inorganic materials.
- 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 G203A.
