Because the coating is highly water
repellent, contaminant’s cannot film
out over the surface.



Our Midsun 570 HVIC™ presents a smooth
finish with superior tracking resistance.


Midsun 570 HVIC™ silicone coating can eliminate or reduce:

  • regular insulator washing and cleaning
  • periodic re-application of greases
  • replacement of T&D components damaged by flashovers.

Midsun 570 HVIC™ silicone coating has proven superiority:
  • in warranting no flashovers from the onset of leakage current
  • over competitors first generation silicone coatings
  • in providing the lowest installed cost in all types of pollution conditions; from road salt spray to fly ash

Midsun 570 HVIC™ room temperature vulcanizing (RTV) silicone rubber coating on glass, porcelain and polymer insulators performs by virtue of its water repellency and its proprietary anti-tracking,flame retardant, adhesion promoter agents. Because the coating is highly hydrophobic contaminant’s cannot film out over the surface.

Frequently Asked Questions:

How long will the coating last?

Longevity depends on a variety of factors. Conditions such as corona and dry-band arcing will age the coating more quickly. Under the very worst conditions, the coating should last for ten(10) years.

What is the required thickness for Midsun HVIC?

Midsun Group feels that, a 15 mil thickness is optimal, based on our long term success.

What effect will less than 15 mil thickness have?

Midsun HVIC’s life is usually determined by erosion, so you will reduce the life if you put on a thinner coat.

Can Midsun HVIC be applied energized?

Midsun HVIC is not formulated for energized application. Midsun Group does however offer Midsun Energized HVIC, which is specially formulated for energized applications.

How should you clean Midsun HVIC coated insulators?

Cleaning should not be required, but if desired, a low pressure water wash will work.

What if I need to remove the coating?


The coating is permanent and should never require removal, simply a quick cleaning with solvent and re-application of coating. If removal is desired the coating can be stripped with a corn cob blast.
