Parylene Vapor Deposited Conformal Coating

30 Years of Parylene Coating Solutions

We provide Parylene Vapor Deposited Conformal Coating services. Parylene Vapor Deposited Conformal Coating is a polymer deposited in vacuum as gaseous nano molecules polymerize to form a thin film of protective parylene barrier. Thickness can be as thin as a micron. This film is inert thus it resists very aggressive chemicals. The film also has desirable electrical properties like a very high dielectric strength. The mechanical properties are also excellent providing a very low coefficient of friction. Parylene Vapor Deposited Conformal Coating is considered by many to be the ultimate conformal coating for the protection of devices, components and surfaces in the electronics, instrumentation, aerospace, medical and engineering industries. Parylene provides exceptional protection for the most extreme environmental conditions.

Parylene Coating Process and Benefits

The parylenes are formed by the pyrolysis of a di-p-xylene (dimer) in a vacuum environment which is then deposited on a cooler (i.e. room temperature) substrate under continuous vacuum. Vapor phase deposition of the parylene polymer allows it to be formed as a structurally continuous film which is truly conformal to the design and structure of the substrate upon which it is being deposited. Parylene can be effectively deposited with excellent accuracy in the thickness range of 0.1 mils to over 2 mils.

Parylene C

The most widely used dimer, providing a useful combination of properties, plus a very low permeability to moisture, chemicals, and other corrosive gases.

Parylene N

Provides high dielectric strength and a dielectric constant that does not vary with changes in frequency. Best selection where greater coating protection is required.

Parylene D

Maintains its physical strength and electrical properties at higher temperatures.

Frequently Asked Questions

Parylene N is the un-substituted polymer obtained by polymerization of the para-xylylene intermediate. Chlorinated parylenesEdit. Repeating unit of parylene C.

Parylene conformal coating is a thin film coating technology used to improve the capabilities of leading-edge technologies. Applied as vapor, the coating layer perfectly conforms to complex shapes and provides complete and even coverage.

Coatings of parylene are often applied to electronic circuits and other equipment as electrical insulation, moisture barriers, or protection against corrosion and chemical attack. They are also used to reduce friction, and in medicine to prevent adverse reactions to implanted devices.
