Earth Pro XL-Defoamer is a powerful defoamer intended for use where mild to severe foaming of water-based drilling systems has occurred. It is effective at all pH ranges, at high temperatures and over a wide salinity range.
Normal treatment for light foam is 0.3-0.9 L/m³, and with more difficult foams, 0.9-1.8 L/m³ may be required.
