General description

Xiameter PMX-200

Application

  • Enhanced performance coatings: A study utilized silicone oil to develop regenerative superhydrophobic coatings, aimed at improving the performance and durability of high-voltage electrical insulators in cold climates. This application highlights the material′s effectiveness in environmental protection and infrastructure longevity (Khademsameni et al., 2024).
  • Durable super-hydrophobicity: Silicone oil was grafted onto rough thermoplastic polyurethane surfaces to create durable super-hydrophobic properties, demonstrating a significant advancement in materials engineering for creating water-resistant surfaces (Tan et al., 2024).
