Printing Inks

Rheology modifier and stabilizers that contribute to improved gloss and adhesion

Each printing process requires an ink or a paste with a specific viscosity and drying behavior. According to their viscosity inks can be grouped by liquid inks and paste inks. In general printing inks and pastes are comprised of four components: Pigments, Resins, Solvents and Additives.

The resins act as binders, binding the other ingredients of the ink together so that it can form a film and bind the ink to the substrate (e.g. paper). The resins also contribute to gloss.

Beside the use in the ink, polymers are also being used as wetting agents in the pigment grinding process to ensure readily dispersible pigments.

Our Solutions

ETHOCEL™ ethylcellulose polymers are being used as high quality rheology modifier, film former and binder in inks for gravure, flexographic and screen printing. Additionally, ETHOCEL™ ethylcellulose polymers act as wetting agents during the pigment grinding process.

In aqueous inks for inkjet printing, POLYOX™ water-soluble polymers are applied as rheological modifiers, dispersant, stabilizer and drag reducer at low addition rates.
