Function

It decreases the fluid loss obviously. Generally less than 100ml.If add the dosage, fluid loss will less than 50ml.

Thickening time decreases regularly as temperature rises; No bad influence on strength development of cement stone.

Not sensitive to dosage, no catastrophe point, can be used in variable density cement slurry system.

Recommended dosage:4.0~6.0%(BWOC)

Applicable in every kind of cement slurry systems, which are composed by every grade of oil-well cement(defined by GB10238 or APISpec10A) 

and other additives(just like silicon powder, drift beads, flyash, bentonite, barite powder and hematite.).


Storage

It should be stored in cool,dry and ventilated areas and avoid being exposed to the sun and rain.

Shelf life:12 months.
