Parylene has numerous outdoor applications. However, a major drawback of most parylene types is limited resistance to direct contact with UV radiation. Daylight is the most common source of UV light. Prolonged exposure to its high energy radiation can cause objects extensive surface damage and lead to eventual malfunction of electrical light-generating assemblies within.
While parylene is an extremely effective conformal coating, its benefits only come into play when it is properly applied. When parylene is either applied incorrectly or is deposited on a surface that is not prepared for adhesion, the coating can become compromised. Luckily, common parylene defects can be identified, planned for and mitigated through proper […]

Recognition of parylene’s excellence as a conformal coating for many product uses has grown along with its application. However, issues of barrier failure, current leakage, poor processing, and cost limit its further development and use.
