Main benefits of Parylene

The Parylene process is a vapour deposition process differing significantly to all of the other liquid conformal coatings available. This difference leads to many unique advantages:

  • Uniform coating – Parylene coatings are completely conformal, have a uniform thickness and are pinhole free. As a result, component configurations with sharp edges, points, flat surfaces, crevices or exposed internal surfaces are coated uniformly without voids.
  • Inert – Parylene coatings is chemically and biologically inert and stable and make excellent barrier material.
  • Excellent electrical properties – Parylene conformal coating has excellent electrical properties: low dielectric constant and loss with good high-frequency properties; good dielectric strength; and high bulk and surface resistance.
  • Optically clear – Parylene is transparent and can be used to coat optical elements.
  • Qualified – Parylene complies with USP Class VI Plastics requirements and are MIL-I- 46058C / IPC-CC-830B listed.
  • Pinhole free – Coatings are truly conformal, of uniform controllable thickness, and are completely pinhole-free at thicknesses greater than 0.5µm.
