Addition method and processing guidance
For optimal performance, defoamers should be added to the grinding material before milling.
If added at a later stage, sufficient high shear force must be applied to ensure good dispersion of the defoamer and prevent cratering.
Complete defoamer effectiveness is achieved 24 hours after incorporation into the system.
