Dispersing agents

DISPEX® and EFKA® dispersing agents for water-based, solvent-based, and solvent-free formulations

Our portfolio of dispersing agents for paints, coatings and ink formulations contains solutions for aqueous, solvent-based, high solids, 100% solids systems and universal pigment concentrates. These polymeric, oligomeric and surfactant-based technologies are known for outstanding color development, viscosity reduction, enhanced gloss and stability as well as suitability for low-VOC and APEO-free systems.

EFKA® PX is highly effective in solvent-based systems, while DISPEX® ULTRA PX is ideal for aqueous applications. Both polymers are characterized by a highly defined architecture, improved colorant stability and broad versatility.

Your universal dispersing agents toolbox

For coatings that must comply with major ecolabel standards, we have developed a unique dispersant formulation toolbox. This set of dispersants enables you to formulate hazard label-free universal colorants, which are used to tint both aqueous and solvent-based architectural paints. Talk to your partners at BASF for support in formulating and developing coatings – they can give you guide formulas for all dispersing additives in conjunction with a variety of pigments.
