GH-8 Retarder for High Temperature Oil Well Cement

GH-8 can absorb on the surfaces of cement hydration to inhibit it contacting with water and forming chelae with Ca²⁺ to prevent crystal nucleus forming early. So it can retard thickening time.

• Normal dosage: 1.0%~2.5%(BWOS), it is sensitive for temperature, should add more with increasing of temperature;

• Reduce consistency of cement slurry and improve the rheology;

• Retard the thickening time efficiently;

• Suitable temperature: circulate temperature under bore is 230℉~320℉ (BHCT).

• Be packed with three-layer plastics bags, 25kg per bag.
• Be kept away from moisture and possible damage of the packages during transportation; be stored in cool and dry situation. Storage life time is two years.
