Performance feature

①Has good effect of filter loss,can resist saturated salt.

②Low cost,can be used in low cost well drilling.

③Resistance to high temperature is not so good,can be used in shallow salt water drilling fluid.

Storage and package

Triad bag enclosed with film bag,net weight:25kg/bag.Stored in cool,drying,ventilated place.

Safety matters

Away from eyes,skin and clothes,otherwise flush with water.
