One of the most important considerations for any conformal coating job is the optical quality of the coating itself--not just for function and reliability purposes, but also for aesthetic value. Today we'll take a closer look at the optical properties of parylene and explore why it matters to you and your project.
What They Are
No matter what you're working on, the chances are high that you'll need to consider the visual element of your project sooner rather than later. When using a conformal coating, this is especially important, as some coatings may interfere with the visibility and reliability of the object, machinery, or other surfaces. The optical properties of parylene, however, offer a wide range of benefits, making parylene a good choice for almost any project.
Here's a closer look at parylene's optical properties:
Parylene has good absorption, which means that different types of light can interact with the coating without impacting appearance. Under almost all circumstances, parylene coating is colorless.
One of parylene's most important properties is clarity. Different application processes will impact clarity, but for the most part, parylene is reliably clear and does not interfere with visibility.
- UV resistance
When combined, oxygen and high levels of UV light can be damaging to parylene coating. However, under controlled circumstances, parylene can offer certain levels of UV resistance.
Why It Matters
Parylene's optical properties come with a lot of benefits. Here are just a few!
Because parylene is clear and colorless, it does not limit (and, in fact, only enhances) the functionality of the surfaces, materials, or machinery it coats.
Parylene coating is strong and long-lasting, which means that even boasting its long list of optical properties, its performance is never impacted.
- Aesthetic value
For projects where aesthetic value is of high importance, parylene is an excellent choice because it can be deposited smoothly and without pinholes, offering clear visibility under almost any circumstances.
