Superiority
SUMMARY
-High purity low dosage highly effective fluid loss additive.
-Specially designed for the application in low density cement slurry system.
-Generates thickening effect on the cement slurry and enhances cement slurry’s suspension stability.
-Used blow temperature of 180℃(356℉, BHCT).
-Features with excellent salt tolerance up to salt-saturation, suitable for both fresh and salt water system.
-When applied, cement slurry system is stable with little free fluid.
-Good compatibility with other additives.
-Applicable with all API classes of cement
-Soluble in cold water ,dry or water mixed when applied and no water quality is required
-Dry-mixed type fluid loss additive CG210S-D can be made when mixing CG210S-P with materials such as slag, silica flour, flyash etc. When CG210S-P is mixed with salt, dual purpose type CG210S-T can be made which can be both water-mixed or dry mixed. The concentration of CG210S-P high purity powder in both CG210S-T and CG210S-D ranges from 35% to 80%
-Liquid product CG210L is made when 20-30% concentration of CG 210S-P high purity power dissolves in water, If not put to use immediately, germicide should be added as to prolong durability.
-The following technical data and parameters are of our standard type of CG210S-P. We are capable of catering tailor-made products and services upon receipt of customers’ individual requirements.

1.5% (BWOC) or 0.75kg/50kg cement |
2.5% (BWOC) or 1.25kg/50kg cement |
Note: Dosage of standard CG210S-P is calculated based on 50kg /sack cement and shall be adjusted when different cement, mixing water and slurry density are applied. When used in high concentration salt water and high temperature conditions, the dosage shall be increased, confirmed dosage is to be finalized based on lab test result.
