Parylene Coatings | The coatings process
Uniform Coating —
Thickness tolerances are typically held to +/- 20% from nominal.
Tolerances as tight as +/- 5% are possible when necessary.
Parylene is inert and insoluble in most solvent systems within its useful range of temperature. Parylene C and Parylene N may be used up to 125°C continuously in the presence of oxygen.
Low Stress Process —
Polymerization of parylene takes place at room temperature. Any object which can be exposed to medium vacuum can be parylene coated.
Optical Clarity —
Parylene C is optically clear. Parylene N exhibits a slight haze at thicknesses over 5 microns.
