Thin polymer coatings for electronic components and sensitive devices
SCS’s Parylene coatings deliver exceptional protection against moisture and chemicals, applicable to a wide variety of substrates, including metals, elastomers, resins, plastics, and ceramics.
These coatings, with uniform thicknesses from a few hundred angstroms to several mils, are pinhole-free and ultra-thin, ensuring minimal impact on the size and weight of components, making them perfect for systems constrained by size, weight, and power (SWaP) requirements.

Corrosion and Chemical Resistance – Parylene acts as a robust barrier against corrosive liquids, gases, and harsh aerospace chemicals, remaining insoluble in all organic solvents up to 150°C.
Dielectric Properties – The continuous thin film coatings produced through the Parylene deposition process exhibit high dielectric strength and low dielectric constants, facilitating the transfer of electrical signals without absorption or loss.
Thermal Resilience – Parylene N, ParyFree®, and Parylene C can endure continuous exposure to air at temperatures of 60, 60, and 80°C respectively for a decade. Parylene HT® has been shown to withstand continuous exposure to air at 350°C, with short-term exposure to 450°C for under 24 hours.
Cryogenic Performance – Unsupported 50.8 μm films of Parylene C can flex 180° six times at -200°C before failure. Steel panels coated with Parylene C and immersed in liquid nitrogen at -196°C have endured impacts exceeding 11.3 Nm.
Optical & UV Stability – Parylenes are optically transparent and provide exceptional UV stability, safeguarding against degradation and discoloration.
SCS’s conformal coatings are perfectly suited for uavs and drones, providing protection for custom OEM systems and enhancing the durability of commercial off-the-shelf (COTS) products not originally designed for extreme conditions.
As drone usage expands across industrial, commercial, and defense sectors, these aircraft must reliably function in challenging weather and environmental conditions.
Autonomous and remotely operated UAVs depend on a variety of electronic systems, including sensors, cameras, flight controllers, mission payload controls, and communication devices, all of which require protection against potential failures.
SCS’s high-performance conformal coating solutions have been rigorously tested under extreme temperatures, vibrations, and environmental conditions, including high altitudes and space. This proven protection meets a range of critical requirements for UAV designs, such as:
Lightweight and Thin – Minimal impact on drone swap budgets, maximizing payload capacity and flight duration.
Unmatched Reliability – Superior protection against moisture, dust, chemicals, and severe weather conditions.
Favorable Dielectric Properties – Safeguards sensitive electronics without interfering with the drone’s RF control, communication, and data signals, ensuring no distortion or disruption even at higher operating frequencies.
Corrosion-Resistant Coatings for UAVs & Drones
