Abstract:
A water-repellent mixture, for drying a solid having a surface with droplets of water attached to the surface by moving the droplets of water, the mixture comprising:i) a halogenated solvent, selected from the group consisting of a totally halogenated molecule and a partially halogenated molecule with at least one hydrogen atom, wherein the solvent is interposed between the droplets of water and the solid surface to carry the droplets of water, after detachment from the solid surface, andii) a copolymeric silicone having a hydrophilic function for surrounding the droplets of water, and, thus, controlling the interposition of the solvent between the droplets of water and the solid surface, wherein the copolymeric silicone is soluble with the halogenated solvent, and is a polyalkylene oxide modified polydimethylsiloxane of formula: ##STR4##where m is 0 to 100, n ranges from 4 to 50, and R is a radical selected from the group consisting hydrogen atom, an alcohol group, an amino group and a polyalkyl group containing 1 to 5 carbon atoms.
