WHAT IS PARYLENE?

Parylene is a conformal protective polymer coating material utilized to uniformly protect any component configuration on such diverse substrates as metal, glass, paper, resin, plastic, ceramic, ferrite and silicon. Because of its unique properties, Parylene conforms to virtually any shape, including sharp edges, crevices, points; or flat and exposed internal surfaces.

VACUUM DEPOSITION

The Parylene is applied at the molecular level by a vacuum deposition process at ambient temperature. Film coatings from .100 to 76 microns can be easily applied in a single operation. No catalysts or solvents are required; and no foreign substances are introduced that could degrade the coated surface.

TEMPERATURE INDEPENDENT PROPERTIES

Parylene exhibits excellent dielectric strength, exceptionally high surface and volume resistivities; and electrical properties that are essentially independent of temperature. It provides a conformal, pinhole-free coating that is unexcelled for corrosion resistance and dielectric protection.

PARYLENE DEPOSITION

Parylene is applied at room temperature with specialized vacuum deposition equipment that permits control of coating rate and thickness. The deposition process takes place at the molecular level as the chemical, in dimer form, is converted under vacuum and heat to dimeric gas; pyrolized to cleave the dimer; and finally deposited as a clear polymer film.

The material is applied at .0002-in per hr. Coating thicknesses from .100 to 76 microns can be applied in a single operation. Typical coating thickness for circuit boards is .001-in.

PARYLENE DIMER TYPES

Parylene dimer is produced in three variations, each suited to the requirements of a category of applications.

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.
