Taking the best of a proven solution, making it even better, Dow Corning launches Sylgard® HVIC+

Utility maintenance engineers around the world have relied on Sylgard High Voltage Insulator Coating (HVIC) for more than 25 years to protect against power distribution interruptions due to arcing and flashover from salt spray, industrial pollutants, and even desert sand.

Sylgard HVIC+ improves on the original RTV coating to provide the best combination of wet electrical performance, tracking resistance, and durability that will assure utility engineers years of reliable operation.

New Sylgard HVIC+ offers:

  • Long-term water repellency and hydrophobicity. This is invaluable to high voltage applications. Without it contaminants on the surface of the insulators become wet and produce a conductive layer, which contributes to an increase in leakage currents, dryband arcing, and ultimately flashover.
  • Resistance to atmospheric and chemical degradation. The coated insulators remain unaffected by salt air, airborne pollutants, rain or humidity.
  • Resistance to arcing and corona. Sylgard HVIC+ exhibits high tracking resistance to reduce damage during salt storms or other severe contamination events.

Apply Sylgard HVIC+ on:

Glass, porcelain and composite insulators, and where improved surface dielectric properties are needed.
Line and station insulators, as well as bushings, instrument transformers and related devices.
Bucket truck booms to increase their surface resistance.
Other applications requiring arc resistance, such as barrier boards used in switch gear and in large motors.

Sylgard HVIC+ requires only one application, eliminating the need for repeated water washing or greasing, which results in significant savings in maintenance and replacement costs.
