Composition based on a fluorohydrocarbon solvent, suitable for removing water from the surface of manufactured articles

Claim 1

A homogeneous solvent composition, suitable for removing water from wet articles, comprising: (a) one or more fluorinated or chlorofluorinated hydrocarbons having a density of at least 1.3 g/ml at 20° C., a boiling point in the range of from 27° to 70° C., optionally in admixture with CH 2 Cl 2 ; (b) from 0.0001 to 0.5% by weight, referred to the dissolving mixture, of a surface-active agent consisting of a salt formed by: (I) one or more diamines of general formula H.sub.2 N--A--NH.sub.2 wherein A is a linear or ramified alkylene C n H 2n containing 4 to 20 carbon atoms, and (II) a monoester or a diester of phosphoric acid and mixtures thereof, of general formula: ##STR3## 19 wherein Q 1 is a linear or ramified alkyl containing from 6 to 20 carbon atoms, or an ethoxylated alkyl having in the chain 6 to 26 carbon atoms and 1 to 4 oxygen atoms in the aggregate, and wherein Q 2 is equal to Q 1 or is hydrogen, the molar ratio between ester and amine in said salt being in the range of from 1:1 to 2:1.
