A process for transferring heat comprising the following steps:

Method for transferring heat

A method of forming a lubricating film on a surface, comprising applying to a surface a multiphasic composition comprising at least one (per)fluoropolyether (PFPE) lubricant, water and from 0.1 to 3% by weight of water of at least one thickening agent, said multiphasic composition having a viscosity, when measured at 21&#xb0; C. at a shear rate of 1 secof at least 10 Pa&#xd7;sec so as to form a layer, and drying said layer to form a lubricating film. The Applicant has found that by the use of the multiphasic composition as above detailed it is advantageously possible to convey to surface to be lubricated the PFPE lubricant by using application techniques (doctor blade, metering rod, . . . ) as those suitable for solid-like greases, while the actual conveyed lubricant behaves in lubrication as an oil, avoiding the use of fluorinated solvents.
