Production Features


Anti-pollution flashover coatings is a new type silicone coatings. It can be long-term stored in sealed container and cured by absorbing moisture in the air.  This product is neutral, has good adhesion performance to insulator, excellent electrical insulation performance, resistance to damp, resistance to corona. Besides, the cured coating has excellent migration performance of hydrophobicity, resistance to UV, rain and hail, excellent outdoor aging resistance performance and long service life. It is mainly used for high voltage line insulators surface of external insulation.

1.Low viscosity, easy to spray, strong operability

2.Good migration performance of hydrophobicity, resistance to water and damp

3.Excellent electrical insulating performance and aging resistance performance
