Cement Leak Resisting Toughening Agent

Brief Introduction:

Form even fibrous network and improve pressure bearing capacity of high permeability formation and small fractured formation to a certain extent.

BCE-200S consist of special fibre and fluid loss control additives. After hydrophilic treatment tof he fiber surface, BCE-200S doesn't agglomerate and is easy to disperse in cement slurry. It can form even fibrous network and improve pressure bearing capacity of high permeability formation and small fractured formation to a certain extent. It can prevent leakage and improve the toughness of cement stone. BCE-200S may increase the slurry consistency a little, with no other side effect. BCE-200S can be dry blended with cement or added into the slurry directly.
