Abstract (en)
Aqueous compositions containing from 1% to 40% by weight of a perfluoropolyethereal compound having a molecular weight ranging from 400 to 5,000 and containing carboxylic end groups, which are salified with an organic or inorganic base, said compositions being useful as lubricating/refrigerating liquids in the plastic cold processing processes of metals, in particular rolling, dishing, drawing and the like.
