What is Parylene

- Oct 17, 2018-

Parylene is a conformal polymer film that has been used as a protective conformal coating for more than 25 years.It provides environmental and dielectric isolation in a variety of applications, including various medical substrates, electronic circuits, industrial and automotive sensors, and archival preservation of documents and archeological samples.


The most important performance specifications for a conformal coating are uniformity and completeness of coverage, and physical, electrical, chemical, mechanical, and barrier properties.Parylene offers significant performance capabilities in both of these areas.


As a dry process non-solvent based coating, parylene is not affected by volatile organic compound (VOC) restrictions, and it is not implicated in the ozone depletion concerns of the Montreal Protocol and other environmental legislation.
