Araldite S-HCEP epoxy systems provide a cost-effective, semiflexible material for composite insulators with benefits like hydrophobicity, easy processing, and high tracking/erosion resistance. It offers material and processing cost savings compared to other options. The epoxy has intrinsic hydrophobic properties and can recover lost hydrophobicity. It can be processed using standard equipment without extra steps like premixing, vacuum prep, degassing, or postcuring. The epoxy adheres well without primers and provides excellent performance in high voltage insulation applications.
