RTV Silicone Electrical Insulation Coating:
Reliable Protection for High-Voltage Systems
Electrogard SiCoat
High-voltage equipment faces stress from weather, pollution, and moisture, which can weaken insulation over time.
RTV Silicone Electrical Insulation Coating acts as a protective barrier that improves electrical safety while extending the service life of high-voltage assets.
RTV stands for Room Temperature Vulcanizing. Once applied, the coating cures at ambient conditions and forms a flexible, strongly bonded silicone layer on the surface.
What Makes RTV Silicone Coatings Essential?
• Reduces static electricity build-up on floor surfaces
• Protects sensitive equipment from electrostatic discharge
• Controls static safely through dissipative or conductive pathways
• Prevents sudden sparks in hazardous environments
• Improves workplace safety and operational reliability
Introducing ELECTROGARD SiCOAT
A premium RTV Silicone High Voltage Insulation Coating developed for demanding electrical environments.
It forms a seamless, non-porous protective layer on glass, porcelain, HTV silicone, and polymer insulators. The coating bonds strongly and stays flexible over long periods.
Its high dielectric strength helps maintain insulation reliability, even under continuous electrical stress. At the same time, it resists UV radiation, corona discharge, and arc exposure.
Designed for Harsh Industrial Conditions
Electrical systems are often exposed to industrial pollutants like fly ash, cement dust, carbon black, and chemical vapours. These contaminants accelerate insulation failure.
ELECTROGARD SiCOAT is resistant to acids, alkalis, industrial pollutants, and airborne dust. This makes it suitable for coastal, desert, and heavily polluted zones.
The coating suppresses leakage currents, reducing flashover risks and improving system safety and uptime.
Where Can It Be Used?
This RTV silicone insulation coating is suitable for both AC and DC systems, offering flexibility across multiple applications.
It is widely used on substation equipment, including transformers, switchgear, and bushings. Transmission and distribution lines across all voltage levels also benefit from its protection.
Air-core reactors, high-voltage machines, and railway electrification systems are common application areas.
It performs well wherever electrical reliability is non-negotiable.
Easy Application, Long-Term Value
ELECTROGARD SiCOAT is a single-component system, which simplifies handling and application. It can also be applied over existing HVIC, provided proper surface preparation is done.
With a recommended thickness of 300–500 microns, the coating delivers consistent coverage and performance.
A Smarter Way to Protect High-Voltage Assets
RTV Silicone Electrical Insulation Coating is not just a protective layer. It is a preventive solution that improves safety, reliability, and long-term performance.
With proven electrical properties, environmental resistance, and field reliability, ELECTROGARD® SiCOAT helps power systems perform better.
