Can parylene be used outdoors?

Posted by Sean Horn on Fri, May 22, 2015 @ 07:30 AM

Parylene can be used outdoors. However, it has one drawback that could limit its suitability in some outdoor applications: sunlight can yellow it. With this in mind, product designers specifying a coating for a product to be used where it will be subject to sunlight should carefully consider the coatings pros and cons before specifying it. Frequently, but not always, it remains the best choice.

Parylene vs Urethane Conformal Coatings

Posted by Sean Horn on Fri, May 15, 2015 @ 08:16 AM

Parylene and urethane conformal coatings share many characteristics. Both are physically strong, resistant to chemicals and mitigate tin whisker formation. This doesn't mean that the two compounds are interchangeable, though. While parylene offers a unique blend of capabilities, many projects choose urethane because of its cost, strength and other advantages.

Best Implantable Device Coating

Posted by Sean Horn on Fri, May 01, 2015 @ 08:41 AM

Implantable devices place a special set of requirements and challenges on their coatings. The moisture and broad mixture of chemicals that are found inside of the body are challenging in and of themselves. However, the body also has needs from the coatings that are placed within it. They need to be non-irritating and inert enough to be harmless. For most applications, the best choice is USP Class VI compliant parylene coatings.

Differences between Parylene and Acrylic Conformal Coating

Posted by Sean Horn on Fri, Apr 17, 2015 @ 09:00 AM

Parylene and acrylic conformal coatings represent two extremes of the types of compounds you can use to coat printed circuit boards, sensors, or other devices. While acrylic is popular and inexpensive, parylene offers some of the best performance of any coating compound.

Best Conformal Coating for Humid Environments

Posted by Sean Horn on Fri, Apr 10, 2015 @ 08:43 AM

Just about every major type of conformal coating provides protection against moisture. If you get a printed circuit board coated with epoxy, acrylic, urethane, silicone or parylene wet, typically all that you have to do is wipe it off. Environments with high humidity pose a different set of challenges. Because moisture is omnipresent in humid environments, the conformal coating doesn't just have to resist water ingress. It also needs to completely seal the coated item. Given this additional requirement, the best choice will usually be either silicone or parylene.

Is Parylene Coating Bio-compatible?

Posted by Sean Horn on Fri, Apr 03, 2015 @ 09:27 AM

Parylene is the most bio-compatible conformal coating currently available. Its chemical properties make it a natural for use in medical and biological applications. In addition, some of its general benefits also make it particularly valuable in healthcare applications. Finally, parylene also enjoys a stringent USP Class VI bio-compatibility certification.

How Easy is Parylene to Rework?

Posted by Sean Horn on Fri, Mar 27, 2015 @ 08:32 AM

When it comes to reworking, parylene's strengths are also its biggest drawbacks. In addition to its ability to comprehensively coat substrates, it is also, by design, very challenging to remove. However, "very challenging" and impossible are two different things. Furthermore, good planning strategy before coating can also help to reduce the need for parylene rework.

Parylene Conformal Coating for Medical Use

Posted by Sean Horn on Fri, Mar 20, 2015 @ 09:29 AM

Parylene conformal coatings have protected medical device components with an extended range of applications for over 40 years. They offer both patients and medical personnel the most reliable level of uniform, biocompatible device-security for cardio- logical and surgical procedures.  Their value and application proliferate, as technology develops.  

Organic Polymers used as Coatings

The overall generic name parylene designates a unique set of organic polymeric coating materials with innumerable applications.  All commercially applied parylene configurations are polycrystalline and linear in nature.
