How are Parylene coatings applied ?

Parylene coatings are applied at ambient temperatures with specialized vacuum deposition equipment. Parylene polymer deposition takes place at the molecular level, where films essentially ‘grow’ a molecule at a time.

What is the typical coating thickness ?

Parylene delivers thinner film than other coating processes, allowing assemblies to be coated thoroughly without increasing their size. The vapor deposition polymerization process allows parylene coatings to be uniform in thickness and completely pinhole free. Parylene coating completely penetrates spaces as narrow as 0.01mm (10 μ).

How many years will the coating last ?

Under suitable conditions and in the right environment, the coating is expected to last decades.

Can the coating be removed ?

Yes, Parylene is a soft polymer and as such physical, mechanical removal is probably the best method to remove the coating.
