USE OF GLYCEROL AS AN AGENT TO IMPROVE THE SELF-DISPERSING PROPERTIES OF A MINERAL MATERIAL TO BE ADDED TO AN AQUEOUS COMPOSITION

摘要

The invention relates to the use, during a step of dry grinding a mineral material, of formulations containing glycerol and/or polyglycerols, as an agent to improve the self-dispersing properties of said mineral material in an aqueous composition. The immediate viscosity of the final composition is thus reduced and kept stable over time. Furthermore, the amount of foam formed during the step of dispersal in the water is reduced.
