- the radiation beam emitted by the radiation source has such a high energy density that the coating can locally be heated so strongly that it evaporates. Surrounding coating areas, which are not exposed to the beam undergo no significant heating, the coating applied there remains unimpaired. In the evaporation process, molecules of the coating are released into the environment and form a gas mixture with the ambient atmosphere, in particular ambient air.
