It can be used in all solvent-based and solvent-free industrial and decorative coating systems. It is especially suitable for wetting, dispersion and stabilization of inorganic pigments and fillers in solvent-free epoxy and polyurethane systems, like flooring or pipe-line coatings. It can be also used to decrease the viscosity of water-based resin-free inorganic pigment concentrates, based on high molecular weight dispersing agents like DISPEX® Ultra PA 4550. In addition, It is suitable for dispersion and stabilization of inorganic pigments and fillers in water-based decorative paints based on acrylic emulsions, achieving a better rheology and improved gloss.
