OBC-G80L is a kind of sulfonic fluid loss additive. It has characters like: anti high temperature, anti-salt, quick strength development, few free water. The product is appropriate to be used in different kinds of water and cement. It is also a kind of widespread use product, which can be used in different kinds of cement slurry systems. OBC-G80L is not only applicable in freshwater cement slurry, but also applicable in salt water cement slurry.
It decreases the fluid loss obviously. Generally less than 50ml.If increasing the dosage, fluid loss will less than 30ml.
Effective salt resistance. It can be used in saturated salt water.
Thickening time increases slightly as temperature increases in the temperature range of 70 to 90. It has no influence on the strength of cement stone.
Not sensitive to dosage, no catastrophe point, safety in use.
