  • Hydrophobizing agent for mineral materials
    Patent number: 12473231
    Abstract: Described herein is a hydrophobizing agent for mineral materials, including: a polyion complex (i) including at least one polycation (i.1) and at least one polyanion (i.2), where the molar ratio of polycation:polyanion in the polyion complex is ?1; and a silicone compound composition (ii). Also described herein are a process for producing the hydrophobizing agent, a method of using the hydrophobizing agent for the hydrophobizing of mineral binders and/or compositions which contain mineral binders and/or materials which include mineral binders, and a binder composition including one or more mineral binder(s) and a corresponding hydrophobizing agent. Also described herein is a process for hydrophobizing materials which include mineral binders, and a hydrophobized material including mineral binders and obtained by this process. Also described herein is a hydrophobized material which includes mineral binders, including the reaction product of one or more mineral binder(s), the hydrophobizing agent and water.
