A universal dispersing agent that fits organic and inorganic pigments


Dispex® Ultra PX 4290 – Novel high-molecular-weight dispersing agent for all pigments in water-based coating systems and printing inks

Numerous standard dispersing agents only show peak performance with a few pigments. However, we have developed a product that covers a broad application range. Dispex® Ultra PX 4290 is a broad-spectrum dispersing agent suitable for both inorganic and organic pigments and fillers used in aqueous coating systems, printing inks and adhesives.

This novel product has exceptional pigment-stabilizing characteristics and also very effectively reduces viscosity, as confirmed by numerous users. Thanks to these properties, Dispex® Ultra PX 4290 allows higher pigment loadings than standard dispersants, without any impairment of its excellent flow characteristics. Further benefits include improved gloss and anti-flooding behavior as well as excellent flocculation stability.
