How Lightweight Coatings Protect Aerospace and Defense Electronics

From satellites and commercial aircraft to uncrewed aerial vehicles (UAVs), the reliability of aerospace and defense electronics depends on their ability to perform flawlessly in extreme conditions. While stresses such as altitude changes, vacuum, vibration, moisture and chemical exposure have the potential to wreak havoc on electronic components, conformal coatings have become essential to providing protection in the midst of these challenges.

Applied as thin, lightweight films that follow the contours of printed circuit boards (PCBs) and components, conformal coatings create a barrier between the electronics and the harsh environments in which they must perform. The coatings' ability to provide dielectric insulation, chemical protection and moisture resistance ensures that mission-critical electronics remain functional on the ground, in the sea, in flight or in orbit.
