Parylene Coating
What is Parylene?
Parylene is the generic name for poly(Para-Xylylene) - a unique polymer series that provides thermal, moisture, and dielectric barrier to any vacuum compatible substrate.
Protection against gases, corrosion, chemical resistant
In general, Parylene coatings provide excellent protection against gases, have excellent corrosion resistance, and are resistant to a wide range of chemicals. Parylene is resistant to environmental influences and UV radiation.
Low dielectric permittivity and co-effecient
In addition, the coatings have a low dielectric permittivity and a low dielectric co-efficient.
Low Moisture Vapor Transmission Rate
Parylene coatings can be used in applications where low moisture vapor transmission rates are required and the parylene types available conform to various industrial standards (e.g. FDA Approved)
Constant Coating Thickness
Constant coating thicknesses can be achieved by implementing controlled and repeatible coating processes.
Conformal Coating
Superior coating performance compeared to liquid coating
Parylene Coating Process
Samples are coated with parylene at near room temperature
