ABSTRACT:
Grinding agent based upon acrylic polymers and/or copolymers for aqueous suspension of coarse mineral materials for applications in pigments.
Grinding agent for aqueous suspensions of mineral materials intended for application in pigments, consisting of an acid acrylic polymer and/or copolymer which is partially neutralized by at least one neutralizing agent having at least one monovalent function.
The grinding agent according to the invention is applicable more particularly to the preparation by grinding of mineral materials such as calcium carbonate, dolomites, calcium sulphate, kaolin, titanium dioxide, intended for pigmentary applications as varied as paper coating, pigmentation of paints, fillers of rubbers or synthetic resins or matting synthetic textiles.
