Which defoamers can be used in metalworking fluids
The use of defoamer in metalworking fluids (MWF) is essential for the lubrication and cooling of metals during a machining process. Defoamer is added to the MWF to reduce or eliminate foam formation. The selection of the right defoamer for a given MWF is important, as the wrong one can cause poor ......
