Pollution Flashover Control
DSAN-S2001-(I) Anti-Flashover Coating
Primer-and-topcoat hydrophobic protection for ceramic and glass insulation exposed to pollution and moisture.
Product overview
What it is and where it fits.
DSAN-S2001-(I) is designed to reduce continuous conductive water films on contaminated outdoor insulation surfaces. Suitability depends on the insulator material, pollution environment, surface preparation and application controls.
Selection starts with the substrate, equipment, operating environment and intended application process.
