CMT-106 can stick on the surfaces of cement hydrate to inhibit contacting between cement and water, also stick on the surfaces of crystal nucleons to prevent their enlarging. So it can retard hydrating of cement slurry.
Product Description
Technical & Engineering Information
CMT-106 consists of various kinds of compounds, such as cellulose derivative and hydroxycarboxylicacid.
Non-poisonous, non-odor, and non-corrosivity.
It can reduce the consistency of cement slurry and improve the rheology.
Retard the thickening time efficiently.
Generally used in oil wells whose circulate temperature under bore is below 110℃.
Preferred to be mixed without water.
Non-poisonous, non-odor, and non-corrosivity.

The ingredient of the cement slurry in the table is: JiaHua G class: cement ,W/C 0.44,
Dosage of CMT-106: 0.1%~1.0% ,Water quality: distilled water
Recommended Treatment
Normal dosage: 0.1% -1.0% (BWOC). It is more efficient if it is used combining with USZ friction reducing additive when middle-deep well is cemented;
It can reduce the consistency of cement slurry and improve the rheology.
Packing and Storage
CMT-106 is supplied in plastic-lined bags with net weight of 25 kg/bag. Keep it away from extreme conditions such as places wet and humid or direct sunlight.
Shelf life: 2 years.
