Aerospace Conformal Coatings: Acrylic vs Silicone vs Parylene

Posted by Sean Horn on Fri, Feb 9, 2018

Conformal coatings composed of acrylic, silicone and parylene polymer materials are valuable for a wide range of aerospace applications, which can push technologies to their limits. Applied to printed circuit boards (PCBs) and related electrical assemblies, conformal coatings maintain device performance through difficult operational conditions. The presence of atmospheric variation, chemicals, hum

Conformal Coating Applications: Liquid vs Parylene

Posted by Sean Horn on Fri, Jan 19, 2018

Conformal coating of an object occurs when an appropriate coating material is applied on-top and around an underlying substrate, to protect it from such environmental and performance concerns as chemical incursion and excess moisture. Liquid organic polymer conformal coatings – acrylic, epoxy, silicone and urethane – prevent:
