Evonik launches hyperdispersant for radiation-curing and solventborne PU inks

Even with the most demanding organic pigments, TEGO® Dispers 695 ensures shorter grinding times, strong viscosity reduction, fine particle size, and ultimate color strength - all while maintaining stability during storage.

“Our TEGO® Dispers 695 is not just an incremental improvement compared to other dispersing additives - it’s a significant technological leap. Developed in close collaboration with our customers worldwide, it delivers unmatched performance,” said Susanne Struck, global head of Market Segment Printing Inks at Evonik Coating Additives.

“For all liquid inks, but especially inkjet inks, this stability is a decisive factor - and TEGO® Dispers 695 clearly excels,” said Tommy Guo, project manager and head of Applied Research and Technology at Printing Inks in Asia Pacific.

The additive is highly polymeric, solvent-free, and 100% active, dissolving easily in a wide range of monomers and organic solvents, including alcohols. It enables formulators to achieve higher pigment loadings without thixotropy, reduced grinding times, and enhanced color strength across radiation-curing flexo, litho and inkjet inks as well as PU-based solventborne inks. Suitable for all types of organic and inorganic pigments, TEGO® Dispers 695 is the go-to choice for outperforming, next-generation ink formulations.

Evonik's Coating Additives business offers a comprehensive portfolio of co-binders for inks, along with a wide range of additives for waterborne, radiation-curable, solventborne, and inkjet printing inks.
