000000275 520__ $$aCycloaliphatic epoxy resins have been used alongside silicones and ceramics for more than 30 years as insulation materials for outdoor applications. Insulators made of cycloaliphatic epoxies offer many advantages overer those made of ceramic or silicones. Standard cycloaliphatic epoxies are construction materials, however, they do not exhibit hydrophobicity as do silicones. A new generation of cycloaliphatic epoxy systems with enhanced hydrophobic properties, hydrophobic cycloaliphatic epoxy try to join the advantages of both cycloaliphatic epoxy resins and silicones The paper presents the laboratory and field test results of comercially available hydrophobic cycloaliphatic epoxy insulators. These insulators exhibit the hydrophobic properties under clean conditions. Unfortunately, when polluted by industrial dust the surface becomes hydrophilic. No hydrophobicity transfer was round even three months after surface contamination. Nevertheless, compared with the standard cycloaliphatic epoxy the hydrophobic cycloaliphatic epoxy offers some advantage under light industrial pollution or sea pollution.
