Patent

CA 2740641

The present invention relates to the use of a combination of at least one comb copolymer having a (meth)acrylic backbone, onto which are grafted side chains that end with a hydrophilic group, and at least one ASE acrylic polymer, in the manufacture of an aqueous formulation based on hydraulic binders. An improvement in the handleability of said formulation is achieved, without causing a segregation phenomenon.

La présente invention concerne l'utilisation, dans la fabrication d'une formulation aqueuse à base de liants hydrauliques, de combinaison entre au moins un copolymère peignes disposant d'un squelette (méth)acrylique, sur lequel sont greffées des chaînes latérales terminées par un groupement hydrophile, et au moins un polymère acrylique de type ASE. On parvient à améliorer la maniabilité de ladite formulation, sans provoquer de phénomène de ségrégation.
