Parylene are chemical vapor deposition pioneers of thin-film polymers. These polymers are ideal for being used as conformal coatings in a variety of applications. Parylene coatings provide a more safe and effective way to preserve fragile components than conventional coatings. Also, traditional coatings like silicone and acrylic fail to provide a uniform and smooth surface as provided by Parylene coating. Conventional coatings usually leave behind gaps and often compromise the general protection of the components. The coating is created at room temperature to eliminate the need for a liquid phase during application. Its unique features enable it to penetrate even the narrowest spaces, providing comprehensive coverage.

Parylene AF4 Polymer is a material that overcomes all such challenges using a unique chemical vapor deposition (CVD) method. This method assures pinhole-free and highly conformal coating at the molecular level. This provides outstanding protection for the most complex geometrics. It provides outstanding protection against moisture, chemicals, and corrosive substances. In this way, it safeguards sensitive components from all kinds of environmental damage. Parylene AF4 Polymer Coating is used for a wide range of applications. These coatings provide a protective barrier that minimizes the risk of tissue irritation and rejection.

The Process of Parylene Coating

Parylene AF4 Polymer Coating is applied in a specialized vacuum system using a 3-stage vapor-deposition process. Parylene is deposited molecule by molecule onto parts placed in the vacuum chambers. It helps in creating an extreme conformal coating that uniformly and smoothly covers grooves, crevices, gaps, and even sharp points. The primary stages of the Parylene coating process are the following:

Vaporizer: The process begins with putting the Parylene AF4 Polymer dimer into the vacuum coating chambers. The solid Parylene coating is in powder form and is fixture into a vaporizer, where it is heated and turns from a solid into a gas.

Pyrolysis: Within the system, the vaporized dimer subsequently flows into the pyrolysis furnace. These are spit into their smaller nonnumeric components. 

Deposition Chamber: A special, room-temperature deposition chamber is used for completing the last phase. By using the deposition process, a thin and highly conformal coating is obtained. 

Advantages of Coating with Parylene

Parylene Coating’s special deposition process is more beneficial than conventional coating methods in many ways.

Conformal Coverage: Parylene coating provides consistent covering for geometries, preventing tiny cracks and gaps that liquid coatings fail to overcome.

Ultra-Thin Films: The coating thickness of the polyethylene usually ranges from a few microns to tens of microns. Such a thin coating provides great protection while reducing weight and size issues.

Barrier Properties: The Parylene AF4 Polymer is considered the best protective layer as it provides an exceptional barrier against different chemicals, oxygen, and moisture. It is ideal for shielding delicate components from environmental deterioration

Biocompatible: Parylene AF4 is ideal for pharmaceutical and medical devices as it is stable and compatible with various applications such as automotive, medical, electronics, and semiconductor industries.

In short, Parylene AF4 Polymer Coating can be used on almost all substrates, such asCTEs, conductors, polymers, metals, and plastics.
