Evonik launches dispersion portfolio to improve inkjet ink receptive coatings

Evonik Coating Additives launched a range of four new AERODISP dispersions based on SiO₂ or Al₂O₃ particles, designed to improve waterborne inkjet ink receptive coatings.

Excellent dot sharpness and high resolution are key supporting the transition from analogue to digital printing, especially for waterborne inkjet inks. In order to achieve high-quality results, it is necessary to control the spreading behavior and fixation of the inks on the substrate.

With the new range of waterborne AERODISP dispersions, Evonik Coating Additives has developed products to ensure high dot sharpness and fixation of ink droplets on ink receptive coatings, also known as inkjet primers.

The AERODISP dispersions can be incorporated by simple stirring and are compatible with many different binders and formulations.

To meet the needs of different applications, two of these new AERODISP dispersions are anionic and two are cationic. This allows for optimal interaction and fixation of the ink on the primer.

The anionic grades are particularly recommended for food packaging and decorative applications as they are compatible with non-ionic and anionic binder systems. The cationic grades are compatible with non-ionic and cationic binder systems, making them the first choice for primers for, such as, textile inks.

“We offer a comprehensive range of wetting agents for waterborne inkjet inks. Ink receptive coatings, or inkjet primers, can ensure the highest resolution when formulated with our new AERODISP dispersions,” said Susanne Struck, Global Head of Market Segment Inks at Evonik Coating Additives.
