Wacker Powersil® 555 R Silicone Dispersion
Categories: Polymer; Thermoset; Silicone; Silicone Rubber

Material Notes: POWERSIL® 555 R Dispersion Coating is a one component liquid silicone RTV system that is designed as an insulator coating for high voltage applications. When exposed to moisture in the air, POWERSIL® 555 R cures to a flexible elastomer with excellent electrical and mechanical properties.

Special features:

  • Excellent unprimed adhesion
  • Excellent unprimed adhesion
  • One component, ready-to-use
  • Easy to apply
  • Sprayable or paintable
Application: Protective coating for glass, porcelain or epoxy insulators and other high-voltage insulations, where contamination causes service problems. POWERSIL® 555 R prevents the formation of wet conductive films and therefore the risk of tracking and especially flashovers.
