Polyphosphates are salts of polymeric chains formed from tetrahedral PO4 structural units. They are good at wetting inorganic pigments and fillers and help to reduce the amount of multivalent cations that disrupt electrostatic stabilisation. In Europe, combinations of polyphosphates and polyacrylate salts are used in mill bases for emulsion paints.
