In the world of electronics and advanced manufacturing, it has become necessary to protect products and their components from exterior elements. Parylene coating is a thin film coating technology used for enhancing the capabilities of leading-edge technologies. There are many different types of Parylene coatings. Product designers use Parylene coating to waterproof electronics, add dry lubricity or improve adhesion to other coatings. These coatings are preferred in applications where reliability and performance matter most.
What Is Parylene Coating?
Parylene is a family of thin, transparent polymer coatings applied through a chemical vapour deposition method. Unlike liquid conformal coatings, which are often dipped, sprayed or brushed, parylene coating is deposited as vapour. This makes it easier to provide comprehensive coverage. It ensures coating each and every internal and external aspect of the surface of the component with an even, pinhole-free layer. Some of the most common types of parylene coatings include
Parylene N: It is typically considered a basic type of coating, as it is useful for diverse applications. This coating has a melting point of 420°C (or 788°F).
Parylene C: It is capable of safeguarding products for up to 10 years in extreme environments. Due to its outstanding moisture and chemical resistance characteristics, Parylene C is used for most products that need a conformal coating for protection
Parylene D: Parylene D has similar characteristics to Parylene C. It provides reliable assembly protection at 100°C (commonly known as the point at which water boils) in oxygen-dominated areas.
Parylene F (AF-4): It is used for its excellent barrier properties and chemical resistance.
Parylene has many qualities that make it preferable for varied applications over its counterparts, such as silicon and epoxy coatings. Parylene works through a chemical vapour deposition process that makes it a 100% conformal coating.
What are the common uses of parylene coating?
Parylene is a versatile material used for serving diverse applications. Some of the application for which it is used are as follows:
Electronics
In electronics products, parylene coating is used to protect components against moisture and threats. It is effective in protecting sensitive circuits from humidity, corrosive gases, and contaminants. This makes it beneficial for many everyday devices
Medical
Parylene is biocompatible, and its chemical resistance properties make it ideal for varied medical devices. It creates a barrier between the device and the body and makes medical treatments safer and more reliable.
Aerospace
It is used in UAVs to make them lighter and enhance battery performance. It also help in safeguarding PCBs and components from humidity, weather hazards, pollution, and other external factors?
