Microemulsions containing perfluoropolyethers.

摘要

Microemulsions based on perfluoropolyethers, comprising: an aqueous medium, a perfluoropolyether having a mean molecular weight of from 400 to 10 000 and perfluoroalkyl end groups; a fluorinated surfactant; and, optionally also a short-chain hydrogenated alcohol or a fluoroalkanol or a water-soluble salt, and microemulsion being permanently stable within a certain temperature range, in which they are obtainable by simply mixing of the components.
