Ten Situations When You'll Need to Know about Electronics Coatings

Deciding the type of coating required for engineering applications is a daunting task; you'll have to know about processes, components, chemical, and mechanical compatibility. Some metal or electric coatings aren't perfect for certain applications. Let's learn about advanced Parylene coating methods, applications, and their benefits. Parylene falls under the category of polymer coatings that are dielectric and moisture resistant. The parylene coatings have a linear or polycrystalline structure. Besides, the structure of these chemical polymers comes allows for uniform and thin coatings. Such coatings can blend at a molecular level with the substrate.

Consequently, the coating will appear more uniform and even across the substrate. Parlyene coatings are applied on heart pumps, stents, and electrical components vulnerable to harsh conditions such as aerospace and automotive industries. Keep reading to know about electronics coatings.

What are the different types of parylene coatings?

Although Parylene C is renowned for ideal properties and versatility, there are four types of Parylene, namely Parylene C, Parylene D, Parylene HT, Parylene N.

Ø  Parylene C: This coating includes a concoction of carbon-hydrogen and a chlorine atom while being extremely moisture-resistant.

 Ø  parylene D: Its properties are similar to that of Parylene C. However, it consists of two chlorine atoms. Although it isn't biocompatible, it can endure temperatures up to 125 degrees C.

 Ø  Parylene HT: It is one of the most durable Parylene coatings and can withstand temperatures of 35O degrees Celsius. While consisting of one fluorine atom, it is highly UV stable.

 Ø  Parylene N: It is the simplest type of parylene consisting of a hydrogen and carbon structure.

 

 Why should you apply a Parylene Coating?

parylene coatings or electric coatings are an ideal solution for shielding several electrical components. Besides, parylene is widely used in instrumentation and medical industries. The advantages of parylene coatings are listed below:

ü  Biologically and chemically inert: Parylene is chemically and biologically inert, making it safe for implantation with little risk of infection or rejection.

 

ü  Transparent: Parylene coatings are completely transparent. Thus, they're perfect for covering optical elements.

 

ü  Stress-free: As parylene coating procedures are carried out at room temperature, this coating doesn't have surface or internal stresses.

 

ü  High resistance to solvents: Components exposed to solvents or have suffered any kinds of damage due to solvents can benefit from parylene coatings.

 

ü  High thermal resistance: Parylene coatings can endure constant temperatures up to eighty degrees Celsius.

 

ü  Hydrophobic: Parylene's hydrophobic property or water repellent properties make it ideal for electronic components.
