Value of Parylene Conformal Coating

  • The Parylene process does not include a liquid phase, thus coating will not pool in low areas, bridge across substrate features, or exhibit liquid properties such as meniscus or capillary action.
  • Parylene film is a pure, polycrystalline and amorphous linear polymer distinguished by superior dielectric, gas barrier and mechanical properties, giving it the ability to meet coating requirements in very thin layers.
  • Low static and dynamic coefficients of friction, giving it dry film lubricity that can be valuable for some applications.
  • The room-temperature deposition process makes Parylene suitable for many substrates, including ferrites, rubbers, silicone elastomers, paper, resins, plastics, silicon, metals and even on granular materials.
  • Since Parylene is highly effective in very thin coatings, delicate substrates such as electronic sensors or diaphragms can be protected without significant mechanical or loading effects.

We offer three (3) commercial Parylene variants with unique electrical and physical properties. We will advise and help you select the most suitable variant and process for your unique product needs.

Parylene Benefits in Brief:
  • Complete Surface Conformability
