Dow Corning 3099 is a grease-like silicone coating especially formulated to give electrical insulators long-term resistance to water filming and flashover.
DOW CORNING 3099 HVIC (High voltage Insulator coating) Compound is a greaselike silicone coating especially formulated lo give electrical insulators long-term resistance to water filming and flashover. Formulation adjustments are incorporated into DOW CORNING 3099 HVIC Compound to extend service life by maximizing performance in contact with high voltage corona stress, ultraviolet light, water erosion, and particulate contamination.
In addition to a high level of flashover resistance, DOW CORNING 3099 HVIC Compound incorporates an arc-resistant filter 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 the DOW CORNING 3099 HVIC Compound is the ease of handling. The compound is easy to spread, not stringy, and shows good adhesion to properly prepared insulators.
DOW CORNING 3099 HVIC Compound is used to give a protective coating to electrical insulators.
