TEGO® Foamex 8880 defoamer emulsion combines the power of siloxanes with bio-based materials

Evonik’s Coating Additives business line is expanding its TEGO® Foamex product range with a new defoamer built on unique hybrid technology that features bio-based polymer and polyether siloxane.

The new TEGO® Foamex 8880 has been developed for easy incorporation into waterborne inks at any stage of ink manufacture and even for press-side addition. The defoamer offers excellent foam prevention and great foam knockdown.

“Different technologies have different strengths. Standard siloxane-based defoamer emulsions are typically added at let-down stage, but are not necessarily the first choice for addition at the press-side,” says Courtney Thurau, Head of Global Market Segment Printing Inks at Evonik Coating Additives.

TEGO® Foamex 8880 is a non-ionic emulsion with a high content (more than 50%) of bio-based materials in the non aqueous phase. It does not contain solvents and mineral oils, and is compliant with numerous food contact regulations.
