CT-CFL^TM 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. CT-CFL^TM is not only applicable in freshwater cement slurry, but also applicable in salt water cement slurry.

CT-RE^TM is a kind of AMPS polymer based retarder. It can prolong the thickening time of cement slurry with a good regularity. It can bring good thickening curve with right angle and no influence on strength development. It has good compatibility with various additives. No sensitive to dosage, no catastrophe point, safe to use.

CT-DFOAMER is a phosphate type defoamer which can effectively eliminates the foaming caused in mixing slurry and has good ability to retard foaming in cement slurry. It has good compatibility with additives in cement slurry system, it can be used in both fresh water and salt water slurry without harm to other normal performances of slurry system and compressive strength development of cement paste.
