According to the company, military and defense electronics operate in environments exposed to temperature extremes, corrosive chemicals, moisture, vibration, salt fog, jet fuel exposure, UV radiation, and mechanical stress. Advanced Coating's parylene conformal coating is applied as a vapor-deposited polymer that encapsulates complex PCB geometries and electronic components with a pinhole-free barrier.
The company noted that traditional acrylic, epoxy, and silicone-based coatings may crack under rapid temperature cycling, absorb moisture over time, or fail to coat complex PCB geometries uniformly. Parylene coating addresses these conditions by covering circuit edges, component leads, and sharp corners commonly found in military electronic assemblies.
Advanced Coating outlined several characteristics of parylene coatings for military PCB applications, including moisture and chemical resistance, dielectric insulation properties, thermal flexibility, lightweight coating performance, optical clarity, and dry film lubrication for moving electromechanical components.
According to the company, the coating is designed to resist water, salt spray, solvents, acids, alkaline products, jet fuels, and chemical fumes in maritime, desert, jungle, and industrial operating environments. The company also stated that parylene’s dielectric insulation properties help protect sensitive PCB circuitry from electrical shorts and signal interference in high-humidity environments where condensation may occur.
Advanced Coating said the coating accommodates thermal expansion mismatches between dissimilar materials, reducing risks of delamination and cracking during temperature fluctuations common in aerospace and field deployments. The company added that parylene coatings introduce minimal added mass and maintain optical clarity for electronics and display assemblies while also reducing friction on moving mechanical and electromechanical components.
Advanced Coating identified several military and defense PCB and electronics applications for parylene coating, including ruggedized circuits and field PCs, drone and robotic systems, guidance and navigation systems, radar devices, communication equipment, wearable electronics, microelectronics, printed circuitry, smart technologies, and box-build assemblies.
The company stated that it is registered to ITAR requirements and compliant with FAR/DFARS government and Department of Defense procurement regulations. Advanced Coating also noted certifications to AS9100 and ISO-27001 cybersecurity standards. According to the company, technicians are trained to IPC Class 3 workmanship standards, including J-STD, IPC-A-600, IPC-CC-830, NASA-STD-8739, and military specification requirements.
Advanced Coating stated that its compliance and documentation processes are intended to support traceability, procurement requirements, and quality standards for defense electronics supply chains.
