Abstract :
The paper deals with the intrinsic improvement of the hydrophobicity of epoxy resins used for indoor and outdoor insulation. The main improvement compared to a surface modification is the implementation of the hydrophobicity in the bulk of the material. Such a newly developed material was compared with a cycloaliphatic epoxy, a LSR-rubber and a commercial hydrophobic epoxy. Beside the basic hydrophobicity, the recovery after corona and plasma exposure and the transfer of the hydrophobicity through a pollution layer was evaluated
