ABSTRACT:
Hydroxy terminated polyoxyethylene homopolymers or hydroxy terminated polyoxyethylene/polyoxypropylene block copolymers mixed with polycarboxylates have been found to be effective dispersants for aqueous, high solids, pigment slurries. The blend provides a simple, efficient means of matching the requirements of a particular slurry, while lowering the anionic loading on a pigment particle.
