Si-COAT® 570™ High Voltage Insulator Coating
One-part room temperature vulcanizing (RTV) polysiloxane coating that is a solution to the problem of insulator flashovers.
Si-COAT® 570™ HVIC is a one-part, room temperature vulcanizing (RTV) polysiloxane (silicone) coating. Its unique and patented formulation provides a highly hydrophobic surface for its entire life. The coating is not affected by UV light, corona discharge, chemical contaminants, salt, extreme temperatures or corrosive environments.
Si-COAT 570 HVIC is engineered with exact amounts of non-reactive, low molecular weight silicone and ingredients with precise particle sizes for optimum performance and reliability.
The benefits are twofold:
Superior retention of hydrophobicity, ensuring a tremendously long life span;
A more robust self-cooling mechanism to protect the surface from physical damage in the case of dry band arcing.
No heat is required to cure Si-COAT 570. This means the free fluid in the coating is not subject to further reactions during the curing process. Thus, more free fluid is available under actual field service, which dramatically enhances coating performance.
Si-COAT 570 HVIC applies very smoothly and easily. This translates into a material saving and superior performance characteristics.
Standard colour is Clay Grey. Custom colours may be available.
