USE OF GLYCEROL AS AN AGENT ENHANCING THE SELF-IMPERATING CHARACTER OF A MINERAL MATERIAL FOR AQUEOUS COMPOSITION

摘要

The invention consists in the use during a step of dry grinding of a mineral material, formulations containing glycerol and / or poly-glycerols, as an agent improving the self-dispersing character in an aqueous composition of said mineral material. The immediate viscosity of the final composition is thus lowered and kept stable over time. In addition, the amount of foam formed during the dispersion step in water is reduced.
