SCS Parylene Coatings: Lightweight, ultra-thin conformal coatings provide rugged protection for unmanned vehicles and support systems.

The use of unmanned aerial vehicles (UAVs) and unmanned aircraft systems (UAS) continues to expand, overcoming long-standing logistical hurdles and increasing consumer convenience. Examples of such systems include:

  • Delivery: Rural, parcel, cargo, medical supplies
  • Industrial: Agricultural, inspection & maintenance
  • Aerial imaging: Mapping, surveying, photography
  • Urban Air Mobility: Transportation, traffic alleviation

UAVs and their support systems rely heavily on a multitude of electronics to complete their given tasks. Circuit boards, sensors, power supplies, actuators, radio frequency devices, cameras and LEDs are used for system propulsion, guidance, positioning, communication and illumination. These components need robust protection from chemical, environmental and weather-related factors, but such protection cannot add significant weight to the overall device.  

Robust Ruggedization and Lightweighting with SCS Parylenes

Ruggedization and lightweighting enable UAV and UAS performance and reliability you can count on. The same trusted, high tech coatings that have protected spacecraft and satellite applications for 50 years are also available to ruggedize electronics and assemblies that power and operate unmanned systems. 

While lightweighting primarily takes place in structural design, the effort can also be applied when choosing protection methods, including coatings. SCS Parylene coatings are applied with specialized vacuum deposition equipment and “grow” a molecule at a time. The coatings can range from hundreds of angstroms to several mils in thickness, but the thin films are typically measured in microns.

In addition to being lightweight, UAVs and their support systems must survive repeated exposure to the elements, namely moisture, humidity, chemicals, salt, dirt, etc. Not only do Parylene coatings provide excellent barrier protection in all of these environments, but because the coatings are applied as a gas, they effortlessly penetrate crevices and tight areas on multi-layer components, providing complete and uniform encapsulation.

As you continue to fine-tune the development of your unmanned systems, know that SCS is right beside you, sharing your concerns for safety, performance and reliability.  Learn more in our eBook or contact us today about the superior reliability and performance solutions that SCS Parylenes can provide for your UAVs and their support systems.
