Characteristics

1,It is suitable to all kinds of mud, due to the excellent thinning property and filtration control capacity and powerful anti-electrolytes capacity

2,Be effective at temperature more than 150~160°C,it can also be used above 200°C when cooperated with lignite derivatives and other temperature-resisting chemicals.

3,FCLS is a good emulsifier for oil in water mud.

Application

FCLS may be added into drilling fluids in the form of aqueous solution or powder. When you change PH index into 9.5~10.5, the quantity of thinner is 0.5~1.0 %. The quantity of thinner is 2.0~5.0% when it used as the controlling of fluid loss.

Package

The net weight of each bag is 25kg. With PE film bag inside and paper-plastic complex valve bag outside.
