Tech-690 belongs to a high molecular weight super dispersant containing multiple pigment groups. It not only has good wetting properties, but also has excellent anti settling, anti flocculation, and anti floating ability. It is suitable for dispersing various inorganic and organic pigments in aqueous systems and has a wide range of versatility. It can be used in the production of resin free color pastes.
