Dispersant for solventborne pigment dispersions

Evonik Industries has launched Tego Dispers 690, designed specifically for solventborne printing inks used in food packaging.

According to Evonik, the ingredients contained in this wetting and dispersing additive are completely compliant with the A list of Swiss Ordinance SR 817.023.21, Annex 6. By using the product in solventborne, PU-containing or binder-free pigment dispersions, high pigment loadings can be achieved due to strong viscosity reduction. Tego Dispers 690 is highly compatible with various PU and NC binder types and works well with organic pigments, carbon blacks, and titanium dioxide. It is especially effective in gravure and flexo inks for lamination applications, says the company.
