Conformal Shield for Circuit Boards

What is a Conformal Coating?

It is a thin polymeric, non-conductive film that conforms to the contours of printed circuit boards and components. Acts as an insulating protective layer encapsulating electronics against harsh or extreme environments.

Protection Against Pests and Salt Spray

Electronic boards in outdoor units generate heat, inevitably attracting pests like geckos, mice, ants, and snakes. Crawling or nesting on boards, these animals cross live traces creating short circuits that instantly destroy equipment.

Technical Benefits

  • Excellent dielectric strength: Prevents electrical arcing and short circuits.
  • Moisture protection: Encapsulates board preventing condensation or water penetration.
  • Thermal tolerance: Withstands heat sink thermal overloads without loss of properties.
  • Maximum adhesion: Firmly adheres to all soldered components on board.
  • UV inhibitor formula: Aerosol includes UV shields reflecting sunlight and maintaining coating integrity during outdoor servicing.
