  • What is the parylene coating process?

  • The parylene coating process consists of four steps that make sure the coating properly adheres to the substrate and sections remain uncoated as needed. The benefits of parylene depend on effective adhesion between parylene and the underlying substrate.

  • What is parylene and what are its applications?

  • Parylene is used in medical, aerospace, military and almost every other industry we can think of. It’s applications are as varied as its benefits and has an impressive list of advantages over other conformal coatings. Taking an even closer look shows that the different types of parylene have their own unique benefits.

  • What materials can be coated with parylene?

  • Because they are transparent, parylene coatings are appropriate for use on medical devices where visibility is key. Most materials that can withstand the deposition process (being in a vacuum chamber) can be coated with parylene. Materials such as paper, plastic, ceramics, chromium, stainless steel, and silicon can all handle parylene.

  • What are the benefits of parylene conformal coating?

  • As you can see, Parylene Conformal Coating provides several exceptional benefits for a variety of different products and uses. With its non-liquid properties, versatility and strength, it is the perfect choice for your coating needs. Parylene is used in medical, aerospace, military and almost every other industry we can think of.
