A polymer with great dispersing power

A polymer with great dispersing power

The design of the dispersing agent is important for the colloidal stabilization of the pigment concentrates and it has also an influence on the end properties of the formulation.

Styrene maleic anhydride copolymers are used for both organic and inorganic pigments to provide superior dispersion stability and lower viscosity systems. These polymeric dispersing agents are less likely to migrate to the surface compared to traditionally used monomeric surfactants. In addition to this, styrene maleic anhydride copolymers are good pigments surface modifiers and have the ability to improve the ink’s or coating’s hydrophobicity, gloss and scrub resistance and are also very compatible with many neutral and alkaline pH latexes and paints.

XIRAN® hydrolyzed solutions (XIRAN® SL) are also used in paraffin wax emulsions acting as hydrophobic dispersing agents.  Their ability to drastically imidize improves the hydrophobicity of the systems.
