Applications
DOC-P81L solids-free suspending additive could be used to modify the stability of low-density cement slurries, without Extenders like microspheres, the slurries be equal or greater than 1.2SG could be obtained. The agent also has a strong effect on the hydration of cement slurries, which makes a higher compressive strength.
Benefits
1. Can prepare cement slurries density equal or greater than 1.2SG without extender like microsphere.
2. A strong effect on slurries stability.
3. Can accelerate cement slurries hydration, which makes a higher compressive strength.
4. Well-adapted with most of common well cementing additives.
5. Convenient to cementing work on the sea due to the liquid form.
6. Can obtain higher compressive strength without extenders.
Features
Significantly greater suspending characteristics than previously available suspending additives.
Normal use of range:
Temperature: ＜60℃
Concentration: 50%
Usage Restrictions:
If the temperature is than 60℃, the thickening time and the compressive strength could be abnormally decreased.
