Additive

TEGO® Dispers 761 W

TEGO® Dispers 761 W is a non-ionic wetting and dispersing additive with focus on pigment wetting. Shows outstanding color strength development and viscosity reduction when used in the millbase for flexo and gravure inks. With carbon blacks, it provides high pigment loadings, high jetness, and long-term stability. Listed on the A-list of Swiss Ordinance 817.023.21, Annex 6.
