HVIC is a one-part silicone RTV dispersion designed to improve the performance of ceramic and non-silicone high voltage insulators and similar apparatus. When properly applied and cured, a smooth elastomeric coating is formed over the surface of the insulator. The silicone surface is highly hydrophobic when new and exhibits a unique ability to recover water repellent after contaminants are deposited on its surface. Interaction between the silicone coating and the contamination occurs, which results in the maintenance of high services resistance and reduced leakage currents, interrupting the process that leads to contamination flashovers.

HVIC also minimizes surface damage from electrical activity during extreme weather events such as salt storms. The coating can be used to impart arc resistance and hydrophobicity to other devices, such as barrier boards used in switch gear and in large motors.
