protectivecorrosion protectionwaterproof

Midsun®‘s HVIC coating is a unique silicone paint formula. This coating extends the life of your products and increases their reliability at a lower cost. It prevents excessive leakage currents, discharge elongation and arcing, minimising the need for maintenance. Description The excellent performance of Midsun®‘s HVIC RTV (Room Temperature Vulcanizing) silicone rubber coating is due to its hydrophobicity and unique adhesion agents, with protective properties against flashover and electrical discharges. The hydrophobicity of the coating prevents the build-up of contaminants on the surface. It offers a long-term solution to breakdown problems. We offer turnkey solutions, which include the application of the coating to insulators installed by an OSHA-certified Midsun® staff member. Midsun’s HVIC silicone resists UV radiation, temperature variations, corrosive environments and aluminium hydroxide pitting caused by arcing in dry strips. This coating is mainly used on polluted sites such as steelworks, cement works and quarries, as well as coastal and petrochemical sites. The HVIC can be used to eliminate or reduce the frequency of the following operations: Regular cleaning of insulators Periodic lubrication Replacement of components damaged by electrical discharges Repair of the silicone coating or core in the case of composite insulators Description of Midsun® ‘s HVIC coating: Flash point: 18°C Dielectric strength: 35.9 kV/mm Dissipation factor at 100 Hz: 0.021 Breaking and erosion resistance at 2.5 kV/min: 1000 hours Dielectric constant at 100 Hz: 3.85 Relative density: 1.28 Viscosity 3.5-5.5 Pa*s Coat thickness: 0.4 mm minimum
