Parylene

Parylene is a polymer that is often used to coat surfaces. All Parylene coatings are produced by a vapor phase process in a vacuum chamber at room temperature. The monomer condenses and polymerizes on the surface, forming a uniform and conformal layer that follows the surface topography. The monomer is produced outside the coating chamber, so the chamber is not heated. Coating takes place at room temperature.

Examples of applications for Parylene coatings:

These examples are intended to give you an overview of the use of Parylene coatings. However, there are many other applications where Parylene can use its unique properties to improve surfaces and protect sensitive components.

• Electronics: Parylene is often used on electronic components and circuit boards to protect them from moisture, chemicals and corrosion. The thin and flexible coating does not affect the electrical conductivity of the components.
• Medical devices: Parylene coatings are used in medical technology to protect implants, medical sensors and components of medical devices. The coating provides a barrier against body fluids and prevents the penetration of bacteria.
• Optics: Parylene can be used as a protective coating for optical components such as lenses, prisms and mirror coatings. It improves resistance to environmental influences and prevents fogging of optical surfaces.
• Micromechanics: Parylene coatings are used in micromechanics and microsystems technology. They provide protection for micromechanical components such as sensors, actuators and MEMS (microelectromechanical systems).
• Protective coatings: Parylene can be used as a general protective coating for a variety of materials and surfaces. It protects against moisture, chemicals, corrosion and abrasion.
• Aerospace: Parylene is also used in the aerospace industry to protect electronic components and parts from extreme environmental conditions such as vibrations, temperature fluctuations and high vacuum.
