Abstract
For the liquid impervious sealing of smallest crevices, chinks, capillaries and/or openings within a housing wall, in particular of electronic or electrical devices, it is proposed to provide the housing wall at least in the area of the crevices, chinks, openings or capillaries with a hydrophobic coating. The advantage of applying a hydrophobic coating is that certain gas permeability can be maintained, so that a gas exchange between the interior of the housing and the environment is possible.
