IV. Application scope
Temperature: Below 180°C (BHCT).
Dosage: The dosage of JXF410S is generally 0.2-2.0% (BWOC), and the recommended dosage is 0.5-1.0% (BWOC).
Special Note: When Cement Drag Reducer JXF410S is used in brine or oil well cement whose actual chemical composition does not meet the API requirements, its performance will decrease significantly.
V. Packaging
Cement Drag Reducer JXF410S is packed in 25kg compound bags; or according to customer requirements.
