General Description

DF NT-90 is a non-toxic blended, alcohol based compound used to prevent and reduce foaming conditions commonly encountered in drilling, work-over and completion, and waste water treating applications. Performs well in both fresh water and brine fluids.



DF NT-90 is normally used at treatment rates of 5 gallons per 200-250 barrels of fluid. DF NT-90 should be slowly added directly to the fluid in a mixing tank. Spraying directly onto foam is the preferred method of treating surface foam.
