High quality fluid loss additive with strong fluid loss control ability, rapid strength development, low free fluid(OBC-G90L).

OBC-G90L is a kind of fluid loss additive based on grafted co-polymer of humid acid and AMPS. It has characters like: strong fluid loss control ability, rapid strength development, low free fluid and applicability to different kinds of cement and water. 

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

*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.
