MOLYKOTE 3099 HVIC
MOLYKOTE 3099 HVIC (High Voltage Insulator Coating) Compound is a greaselike silicone coating providing long-term water and flashover resistance for electrical insulators. MOLYKOTE 3099 HVIC Compound is a specially formulated silicone coating designed to protect electrical insulators from the damaging effects of high-voltage corona stress, ultraviolet light, water erosion, and particulate contamination. Its unique formulation includes an arc-resistant filler that inhibits arc growth and prevents glaze damage, thus maximizing insulator performance and longevity. The compound's greaselike consistency allows for easy application and ensures good adhesion to properly prepared surfaces.
Application is straightforward, requiring initial cleaning of the insulator surface to remove any organic materials or detergents. The compound can be applied manually using a cloth pad or bristle brush, or via airless spray equipment after dilution with a suitable solvent to achieve the desired viscosity. A coating thickness between 1/16 inch and 1/8 inch is typically achieved through hand application, ensuring complete and even coverage. Its gray, opaque color aids in visual inspection of application.
In addition to a high level of flashover resistance, MOLYKOTE 3099 HVIC Compound incorporates an arc-resistant filler that inhibits arc growth. This helps protect the insulator from glaze damage when the coating s water repellency is significantly diminished and arcing is experienced. Another benefit of MOLYKOTE 3099 HVIC Compound is the ease of handling. The compound is easy to spread, not stringy, and shows good adhesion to properly prepared insulators
