The present invention relates to a composition for producing a coating for components of a turbomachine having anti-ice properties, wherein the composition comprises a binder which comprises at least one silicon-organic constituent, ceramic particles, boron nitride particles and a solvent and also polytetrafluoroethylene and/or graphite. The ceramic particles can have an average or maximum grain size of less than 4 μm and the boron nitride particles can have an average or maximum grain size of less than 12 μm. In addition, the present invention relates to a process for producing a coating by means of such a composition and also a coating produced in this way and a component provided therewith.
