Silicone-based Defoamer
FC-D63L belongs to professional silicone-based defoamer tailored for oilfield drilling fluid systems. The product adopts uniform stable formula, featuring odor-free composition and mild non-irritating traits for on-site operation.
It rapidly eliminates foams produced in drilling fluid preparation procedures and suppresses new bubble generation amid mud blending work. Featuring quick defoaming response and superior defoaming efficiency, it solves foam overflow, pipeline blockage and system volume instability commonly seen in slurry configuration.
