EVONIK: TEGO® Dispers 688 is a premium dispersant for matte UV-curable coatings and printing inks. Processing, and thus productivity, can be improved during manufacturing and continuous application of the coating due to the excellent rheological profile. Low thixotropy, low viscosity and good yield points can be seen even with the highest concentrations of matting agents. Constant matte and gloss levels after storage of the coatings, even at high usage of matting agents, help to manufacture premium matte surfaces.
