Can Color be Added to Parylene?

Posted by Sean Horn on Fri, Oct 9, 2020

Parylene is a conformal coating exhibiting extraordinary properties such as high mechanical strength and biocompatibility. It is a transparent (colorless) film in the UV-V is range of the solar spectrum (Parylene N and C absorb below ≈280 nm). The high transmittance of the polymers in the visible region (90%) make them eligible for use in […]

Can Parylene be Layered?

Posted by Sean Horn on Fri, Oct 2, 2020

Multilayer conformal coatings are advantageous in resolving diffusion or stability issues. A vast amount of knowledge is available in the literature about the use of multilayered stacks of Parylene and stacks making use of different intermediate materials such as metals and so on. Mostly, use of Multiple layers of Parylene C was commonly reported for […]

What is the Service Life of Parylene?
