An all-purpose dispersing agent for organic pigments

Would you like the flexibility of a dispersing agent that is suitable for a broad application range and achieves top results with organic pigments in water-based flexo and ink-jet printing?

We recommend Dispex® Ultra PX 4290 – our novel high-molecular-weight dispersing agent for all pigments in water-based ink-jet and resin-free pigment concentrates for water-based flexo applications.

Numerous standard dispersing agents only show peak performance with a few pigments. However, we have developed a product that covers a wide application range. Dispex® Ultra PX 4290 is a broad-spectrum dispersing agent suitable for organic pigments in water-based ink-jet and resin-free pigment concentrates for water-based flexo applications.

This novel dispersing agent 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.
