For each waterborne ink, finding the right type of dispersant is a very complicated process. Another difficulty is ensuring broad compatibility with various let-down resins. When blending pigment bases and let-down vehicles, pigment shocking can occur with the wrong dispersant – particularly in resin-reduced and resin-free grinds.
TEGO Dispers 780 W is Evonik’s new and green dispersant for printing ink, offering an excellent choice for resin-reduced as well as resin-free grinds. It is a polymeric, slightly anionic wetting and dispersing additive for high-quality waterborne ink formulations. It is an excellent choice for resin-containing, resin-reduced as well as resin-free grinds. TEGO Dispers 780 W provides excellent pigment stabilization for organic and inorganic pigments.
