Comelec. Parylene coating specialist

Parylene is the generic name of a polymer coating, done by evaporation under vacuum at room temperature (CVD). This original deposition process brings interesting quality to the coating:

conformability
thin layer
pinhole free
high penetration power

The Parylene film is transparent, with a low dielectric permittivity, showing excellent thermodynamic stability (resistant to the solvent and thermal endurance). The coating is biocompatible and biostable as well.
Its properties make it especially reliable as a protection layer for sensitive elements (barrier against the environment or insulator protection).
Parylene is widely used in micro and nanotechnologies, electronics, medical, defence, watch, pharmacopoeia industries…

Parylene Deposition Process

The dimer is sublimed under vacuum and heated to a dimeric gas. The gas is then pyrolized to cleave the dimer to its monomeric form. In the room temperature deposition chamber, the monomer gas condenses on all surfaces and spontaneously polymerises to form the Parylene film. The thickness of the coating depends on the requirements of the end use.
