Germany's Evonik unveils TEGO foamex 8420 for superior ink quality

Some waterborne inks and varnishes, particularly overprint varnishes, contain high levels of foam-stabilizing surfactants like DOSS (diisooctyl sulfosuccinate). The same is true for various pigment grinds and inks and the foam-stabilizing raw materials contained, making them exceptionally difficult to defoam.

The new TEGO Foamex 8420 is specifically formulated to address these challenges, delivering maximum defoaming power in waterborne varnishes and inks.

“Over the past several years, we've developed a comprehensive portfolio of high-performance defoamers for the ink industry,” says Susanne Struck, Global Head of Market Segment Inks at Evonik Coating Additives. “These TEGO Foamex products offer tailored compatibility, effectiveness, and excellent food contact compliance, in both siloxane-based and siloxane-free options. TEGO Foamex 8420 is a perfect complement to this portfolio.”

Evonik Coating Additives offers a broad range of co-binders for inks, along with a wide selection of additives for waterborne, radiation-curable, and solvent-borne printing inks and inkjet inks.
