Evonik’s Coating Additives Business Line launched a defoamer, TEGO Foamex 852 that provides a unique combination of effectiveness and compatibility.
This new, patent-pending technology offers formulators a new level of freedom.
TEGO Foamex 852 provides critical additional defoaming strength and remains just as compatible.
The new defoamer was specifically developed for printing ink applications and can be used to successfully meet Swiss A, FDA and China GB guidelines.
TEGO Foamex 852 is a siloxane-based defoamer for waterborne formulations, is 100% active and thereby also solvent-free.
Further product benefits include excellent shear stability and long-term effectiveness, which is particularly relevant for long print runs or if the printing ink must be stored for long periods.
The defoamer can be added at any stage of the printing ink manufacturing process.
