Abstract
A drying composition according to the invention is composed of a solution of a surface-active agent in a mixture of a fluorinated hydrocarbon and of a polyfluorinated alcohol of formula: Rf-(CH2)n—OH (I) in which n is equal to 1 or 2 and Rf represents a linear perfluoroalkyl radical containing from 2 to 8 carbon atoms.
Claims12
Dewetting composition, characterized in that it is composed of a solution of at least one surface-active agent in a mixture of at least one fluorinated solvent and of at least one polyfluorinated alcohol of general formula:
- Rf-(CH2)n—OH (I)
- in which n is equal to 1 or 2 and Rf represents a linear or branched perfluoroalkyl radical containing from 4 to 8 carbon atoms.
