FOAM BAN® Defoamers for Tank Side use in Aqueous Metalworking Fluids

Foam minimization during the use of aqueous metalworking fluids (MWFs) is required to maintain effective lubrication, heat removal, and prevent overflow of sumps. For these reasons, MWF formulations commonly contain defoamers, which control the foam as it forms by disrupting the interfacial energies that stabilize the foam bubbles.
