Parylenes

Many years of scientific and engineering research went into the development of Parylene coatings. In 1947, a physical chemist in Great Britain, Michael Szwarc, was experimenting with the common solvents in the xylene family. He discovered that the pyrolysis of xylenes, under vacuum formed thin polymer films with very interesting properties.

In the late 1960s, William Gorham, at Union Carbide, devised an efficient method of depositing these films on surfaces. This ushered in age of Parylene coatings deposited by Chemical Vapor Deposition systems. Parylene film is an inert linear chained polymer. It is essentially a long, high molecular weight chain of Carbon, Hydrogen and sometimes Chlorine, Fluorine and other compounds attached to an aromatic carbon ring structure.

Parylene coatings can be used for a variety of applications thanks to the following properties:

  • Optically transparent
  • Pin-hole free
  • USP Class VI biocompatible
  • Relatively thermally stress-free
  • Excellent abrasion and cut resistance
  • Hydrophobic
  • Salt Resistant
  • Fungus and bacteria resistant

What is Parylene?

Parylene is a thin film that when bonded during a deposition process becomes a thin protective coating. Unlike liquid coatings, parylene completely penetrates all crevices and uniformly coats surfaces such as sharp points, cavities, edges, corners and even the minutest pores. Read more…

Parylene Properties

Different varieties, or “chemical variants”, of parylene exhibit very different properties. Our diX parylene has consistently served the needs of companies across many industries, the majority of whom acknowledge the importance of a pure dimer for better coating results. Our Kisco diX brand of parylene is the recognized market leader in product purity. Read more…

Coating Process

Parylene application is a true chemical vapor deposition (CVD) sequence. The utilized used in applying parylene consists of three primary components: a Vaporizer, A Pyrolizer, and a Deposition chamber. The dimer, in its original powder form, is loaded in the Vaporizer, and the materials to be coated are loaded downstream in the deposition chamber. Read more…
